Pentagonal vs Quadrant Shower Tray: Which Is Right for Your Bathroom?
This guide is for homeowners, bathroom designers, and fitters in the UK who are choosing between a pentagonal and a quadrant corner shower tray and want a straight answer grounded in real installation experience — not just a product spec sheet.
In 15 years of fitting bathrooms across London, this is one of those decisions that looks minor on a product page but changes the feel of the room once it is installed. A shower tray shape affects comfort, entry width, and how cramped the corner feels on a daily basis.
This comparison is based on current product specifications and direct hands-on experience fitting both shapes in UK homes. Where dimensions or claims come from the manufacturer's product pages, that is noted.
This article focuses on two specific products: Durovin's Pentagonal Acrylic Shower Tray and the Quadrant Non-Slip Acrylic Shower Tray. It is worth noting upfront that quadrant shower trays also come in a standard acrylic finish without the non-slip surface treatment — so the quadrant shape itself is a separate question from whether you choose the non-slip variant. That distinction is covered in its own section below.
Both compared products use an acrylic top with a fibreglass backbone, a 90 mm waste outlet, and a slimline front profile of 40 mm. Both are rated to a 300 kg load-bearing capacity. The core difference is not build quality — it is shape geometry, available size range, surface finish, and who uses the bathroom.

What Are Pentagonal and Quadrant Shower Trays?
- Pentagonal shower tray
- A five-sided tray designed to sit in a bathroom corner. Two sides run along the walls; the remaining three sides form the front of the tray, creating a faceted angular front edge. The shape gives a more architectural appearance compared with a smooth curve.
- Quadrant shower tray
- A quarter-circle tray designed to sit in a bathroom corner. Two sides run along the walls; the front forms a single curved arc. The curved front softens the corner visually and reduces the amount of floor space the shower claims in the room's circulation path. Quadrant trays are available in two surface variants: standard acrylic (smooth finish) and non-slip (textured surface treatment). The shape is the same — the difference is purely the surface underfoot.
Both shapes are corner shower formats and both pair with matching corner enclosures. They are not interchangeable — a quadrant enclosure will not sit correctly on a pentagonal tray even when the overall footprint dimensions appear similar.
TL;DR
Quick verdict
- Choose a pentagonal shower tray if you want a sharper, more architectural look and your layout benefits from straight front edges rather than a full curve.
- Choose a quadrant shower tray if your bathroom is tight, you want a softer curved front, or slip resistance is a priority.
- For most compact UK bathrooms, a quadrant tray is the easier recommendation — it fits smaller corners (from 800 × 800 mm), is safer underfoot, and the curved front softens movement through the room.
- For design-led en-suites where you want a less common shape, a pentagonal tray can look smarter and more intentional.
- If children, older users, or balance concerns are part of the brief, the non-slip quadrant tray has a genuine everyday advantage over both the pentagonal and the standard quadrant acrylic surface.
- If you want the quadrant shape but the non-slip texture is not a priority, a standard acrylic quadrant tray gives you the same curved format with a smooth finish — worth checking the Durovin range for availability.
Head-to-Head Comparison
The following comparison is based on live product data from the Durovin Bathrooms website and notes from real UK installations of both formats.
| Feature | Pentagonal Shower Tray | Quadrant Non-Slip Shower Tray |
|---|---|---|
| Shape | Five-sided with straight front sections | Curved quarter-circle front |
| Available sizes | 900 × 900 mm, 1000 × 1000 mm | 800 × 800 mm, 900 × 900 mm, 1000 × 1000 mm |
| Surface safety | Standard acrylic finish | Non-slip textured surface |
| Material | Acrylic top with fibreglass backbone | Acrylic top with fibreglass backbone |
| Front profile height | 40 mm | 40 mm |
| Waste outlet diameter | 90 mm | 90 mm |
| Load-bearing capacity | Up to 300 kg | Up to 300 kg |
| Best for | Design-led corners, modern angular rooms | Small bathrooms, family use, safer footing |
| Main trade-off | No 800 mm option; no non-slip surface claim | Curved look is less sharp if you want an architectural style |
Key takeaway: these two trays are closer in core construction than many shoppers expect. The decision is really about shape geometry, available size, and who uses the bathroom.
Note: the table above compares the pentagonal tray against the non-slip quadrant variant specifically. A standard acrylic quadrant tray — same shape, smooth surface — is also available in the Durovin range. See the standard vs non-slip section below if that distinction matters for your project.
What Changes in a Real Bathroom?
1. Entry and circulation
A quadrant tray usually feels easier in a small room because the rounded front softens the corner. You are less likely to clip your shin on the tray edge when walking past a basin unit or WC. In one London terrace project — a narrow 1.8 m × 2.1 m bathroom — switching from a straight-edged format to a quadrant tray made the difference between a room that felt claustrophobic and one the client was genuinely happy with. That kind of spatial gain matters more than people admit, especially in tight en-suites where the shower sits close to the doorway.
A pentagonal tray gives you a more defined front line. That can look excellent in a clean, modern layout, but it needs more consideration from the rest of the room. If the basin projects too far or the toilet sits too close, those straight front edges make the corner feel busier and harder to move around.
2. Surface safety
This is the biggest functional difference between these two Durovin models. The Quadrant Non-Slip Acrylic Shower Tray includes a non-slip textured surface, while the pentagonal model does not carry that claim on the current product page.
For younger, confident households that may not matter much. For older users, children, or anyone renovating a main family bathroom, I would not brush this aside. Falls in the bathroom remain one of the most common causes of home injury in the UK — a non-slip surface is a practical, daily benefit rather than a specification line to skim past.
3. Size flexibility
The quadrant tray offers one practical advantage in range breadth: it starts at 800 × 800 mm. That size is not luxurious, but it is often the difference between fitting a proper shower and giving up on the corner entirely. In Victorian terrace conversions and modern city apartments, that 100 mm difference — compared to the pentagonal's 900 mm minimum — can determine whether a corner shower is possible at all.
The pentagonal tray starts at 900 × 900 mm. That makes sense if you have more room and want the shape for design reasons, but it is less forgiving for constrained layouts.
Pentagonal Shower Tray: Pros and Cons
Why I would recommend it
- The angular shape looks more tailored and architectural than a standard curved tray — suited to bathrooms with square-edged sanitaryware and frameless enclosures.
- The Durovin model uses the same fibreglass-backed acrylic construction as the quadrant, rated to 300 kg, so you are not sacrificing core strength for aesthetics.
- The 900 mm and 1000 mm sizes align with common UK corner shower footprints for adults who want reasonable comfort.
- The slimline 40 mm front profile suits modern low-profile shower builds.
Where I would be careful
- There is no 800 mm option, so it will not fit the tightest UK bathroom corners.
- There is no stated non-slip surface, so it is not the first choice for households with older users or young children.
- The enclosure and wider layout need to suit the pentagonal geometry — it looks wrong paired with round-edged sanitaryware or a curved bath.
Quadrant Shower Tray: Pros and Cons
Why I would recommend it
- The curved front is easier to live with in a compact room because it smooths the walking route around the corner.
- The non-slip textured surface is a proper day-to-day benefit — important for family bathrooms and ageing-in-place projects.
- The inclusion of 800 mm, 900 mm, and 1000 mm sizes makes it adaptable across en-suites, family bathrooms, and budget refurbishments.
- It pairs easily with the wide UK market of quadrant enclosures, making the enclosure selection straightforward.
Where I would be careful
- If you want a sharper, more individual look, a quadrant tray can feel expected — it is the most common corner shower format and will not stand out in a design-conscious space.
- Non-slip finishes require consistent cleaning. Soap residue and limescale build-up will reduce the surface texture's effectiveness over time if the tray is neglected.
Standard Quadrant vs Non-Slip Quadrant: Which Variant?
Once you have decided the quadrant shape is right for your bathroom, there is a second decision: standard acrylic surface or non-slip surface? These are the same shape and the same corner format — the difference is entirely underfoot.
| Feature | Standard Quadrant Shower Tray | Quadrant Non-Slip Shower Tray |
|---|---|---|
| Surface finish | Smooth acrylic | Textured non-slip acrylic |
| Safety underfoot | Standard — suited to confident users | Enhanced — suited to all user types |
| Cleaning | Very easy — smooth surface wipes down quickly | Easy, but texture requires a brush to clear soap residue fully |
| Visual appearance | Clean, minimal look | Slight surface pattern visible on close inspection |
| Best for | Design-led showers, younger households, en-suites used by adults only | Family bathrooms, mixed-age households, ageing-in-place projects |
When to choose standard acrylic quadrant
If the bathroom is an adult-only en-suite, the users are confident on their feet, and a clean uninterrupted surface finish matters to you , a standard quadrant tray is a perfectly reasonable choice. The smooth acrylic is also marginally easier to keep spotless, since there is no texture for soap scum to settle into.
When to choose non-slip quadrant
If the bathroom is shared by children, older relatives, or anyone who would benefit from extra grip underfoot, the non-slip variant is the safer default. The texture is not dramatic , it is also not a rubber mat or a heavy pattern but it does reduce slip risk on a wet surface without changing the look of the room in any meaningful way. For most family main bathrooms, I would default to non-slip without much debate.
Which One Should You Choose?
Quick decision guide
Choose pentagonal if...
- You have a 900 mm or 1000 mm corner available after tiling
- You want the bathroom to look modern and less standard
- Users are confident on their feet and non-slip texture is not a priority
- You are pairing with an angular enclosure or frameless glass
- The room has at least 650–700 mm of clear floor beside the tray
Choose quadrant if...
- Your corner measures as little as 800 × 800 mm after tiling
- You are designing for children, older relatives, or balance concerns
- The room is tight and every millimetre of circulation matters
- You want the most flexible, straightforward corner-shower answer
- You want the broadest choice of matching enclosures on the UK market
If pentagonal fits your brief, start with the Pentagonal Acrylic Shower Tray.
If quadrant fits your brief, the Quadrant Non-Slip Acrylic Shower Tray is the more practical fit.
My honest default recommendation
For the average UK small bathroom, I lean quadrant first because it solves more real-life problems — fits smaller corners, is safer underfoot, and the curved front is easier to live around in a confined space. I lean pentagonal when the room has enough breathing space and the homeowner wants a more distinctive look. If you are genuinely unsure: measure the corner after tiling — if it is under 900 mm, the decision is already made for you.
UK Buying Notes That Matter Before You Order
Based on current guidance from Screwfix's shower tray buying guide, Mira's quadrant enclosure guide, and Drench's anti-slip ratings explainer:
- Measure after tiling, not before. Tiles typically add 10–20 mm per wall — two tiled walls reduce your corner by 20–40 mm total. Always work from the finished dimension.
- Check enclosure compatibility. Pentagonal and quadrant are not interchangeable shapes. Confirm the enclosure is designed for the tray shape you have chosen, even when the stated widths appear similar.
- Think about who uses the bathroom. Safety underfoot, cleaning habits, and confidence of movement matter more than showroom appearance once the room is in daily use.
- Do not ignore cleaning. Acrylic trays are easy to maintain, but soap residue and limescale will shorten the good looks of any tray — and reduce the effectiveness of non-slip surfaces — if neglected. A weekly wipe with a non-abrasive cleaner is sufficient.
- Treat slimline trays seriously during install. A 40 mm low-profile tray still needs proper support, correct levelling, and thorough sealing at the wall junctions.
- Check product standards. For shower trays sold in the UK, look for compliance with BS EN 14527 (shower trays for domestic purposes). Confirming compliance gives a baseline for dimensional accuracy and durability.

What Is Changing in UK Shower Design?
Design direction worth knowing
Two shifts are visible in UK bathroom refurbishments right now. First, walk-in and wet-room formats are growing in new-build and higher-budget refurbishments — they remove the corner tray question entirely by extending the shower across a larger floor zone. If budget and space allow, this is worth considering as an alternative to either corner format.
Second, within the corner shower category, there is a clear move toward larger base sizes. The 1000 × 1000 mm format is increasingly the starting point for adult comfort rather than a premium option — particularly in en-suites designed for everyday primary use. If budget allows, stepping up from 800 or 900 mm to 1000 mm typically adds under £100 to the tray cost and makes a noticeable difference to daily comfort.
Neither trend makes pentagonal or quadrant obsolete — but knowing the direction is useful before you finalise your brief, especially if a wet-room conversion is within budget.
Frequently Asked Questions
Is a pentagonal shower tray better than a quadrant tray for small bathrooms?
Not usually. In very small bathrooms, a quadrant tray is generally the easier choice because the curved front improves movement and the range includes an 800 × 800 mm option. The pentagonal tray starts at 900 × 900 mm and needs more surrounding floor space to work well.
Does a quadrant shower tray feel smaller inside?
It can feel slightly more enclosed visually, but in tight bathrooms it often works better overall because the curved front reclaims circulation space outside the shower, making the whole room feel more usable.
Is a non-slip shower tray worth it?
Yes, especially in family bathrooms, ageing-in-place projects, or any bathroom where multiple users with varying confidence share the space. A non-slip surface is a passive, permanent safety feature that does not require the user to think about it.
Are pentagonal shower trays outdated?
No. They suit modern bathrooms well because the angular shape looks cleaner and more deliberate than a standard curve, particularly when paired with square-edged sanitaryware and frameless glass enclosures.
Do both trays suit modern slimline installations?
Yes. Both Durovin trays use a slimline front profile of 40 mm, so either can work in a modern low-profile shower build when properly levelled, supported, and sealed.
What is the difference between a standard quadrant shower tray and a non-slip quadrant tray?
The shape is identical — both are quarter-circle corner trays. The only difference is the surface finish. A standard quadrant tray has a smooth acrylic surface; a non-slip quadrant tray has a textured surface treatment that improves grip on a wet floor. If safety underfoot is a priority, choose non-slip. If you prefer a clean smooth finish and your users are confident adults, standard acrylic is a reasonable choice.
What is the difference between shower tray shapes for a corner bathroom?
The main corner shower tray shapes are quadrant (quarter-circle curved front), pentagonal (five-sided with faceted straight front), and square or rectangular (flat front, right-angle corners). Quadrant and pentagonal both sit in a 90-degree wall corner. The choice between them comes down to available space, user safety needs, and the visual style of the room.
Final Thoughts
There is no universal winner here, which is exactly why this choice matters.
If your priority is safer footing, flexible sizing, and easier movement in a compact bathroom, buy the Quadrant Non-Slip Acrylic Shower Tray. If your priority is a more design-led corner with stronger visual lines, buy the Pentagonal Acrylic Shower Tray.
The most reliable buying rule is simple: measure the corner after tiling first, then let shape and safety requirements narrow the choice. Style can settle the tie — but only once the practical constraints are met.
