The WetBase® Linear 1700 x 1000mm wet room shower tray is a 30mm former with a linear channel drain across the short end and the fall built in. It comes complete with a McAlpine fast-flow drain and a reversible channel cover: brushed stainless steel on one side, tileable on the other.

Your installer sets the waste outlet by drilling a 51mm hole along the channel, so the connection can be placed clear of joists. Made in Germany with a 20-year manufacturer's guarantee, the tray suits timber and concrete sub-floors and can be trimmed by up to 50mm per side. Channel covers come in 12 matched finishes, and a Mapei tanking kit and a second drain outlet are available as add-ons.

📏
83mm shallow depth
One of the shallowest wet room drain outlets available - built for installations where joist depth is limited.
⬆️
Higher water exit point
The waste exits higher up the outlet body rather than at the very base - giving installers the extra height needed to achieve a proper fall on shallow floors.
🔧
Multi-angle knuckle joint
A jointed elbow between the trap and waste pipe creates additional fall on demand - angle it to suit the run, rather than being fixed to one direction.
🔄
360° rotating outlet
The outlet body rotates freely through 360°, so the waste pipe can be run in any direction to suit the joist layout beneath.
💧
34 L/min certified flow rate
Tested under a constant 15mm head of water in accordance with clause 5 of BS EN 274-2:2002 - a recognised European standard for waste fitting performance.
✅
No screeding required
Pre-formed drainage fall built in at the point of manufacture. Ready to install straight from the box.
■
Tile direct - no primer
Cementitious top coat is non-porous. No primer or preparation needed before tiling.
↻
Reversible channel cover
Brushed finish one side, fully tileable the other - match the drain cover to your floor.
🎨
12 matched drain finishes
Brushed stainless steel, matt black, rose gold, satin gold, satin copper, satin bronze, satin nickel, satin brass, Flova bronze, aged bronze, gunmetal grey, matt white.
🏆
20-year guarantee
Manufacturer's warranty on every tray when installed to the supplied specification.

The WetBase® Linear is manufactured from a lightweight XPS foam core with a cementitious top coat, giving a non-porous, tile-ready surface. The pre-formed fall means no screeding on site. Each kit is supplied complete with a McAlpine CD-ST90-1.5T shallow drain assembly, stainless steel grill, and reversible channel cover. A tanking kit to seal all floor and wall joints is required but not included as standard — available as an optional add-on at checkout.

A standout feature of the WetBase® Linear is the McAlpine CD-ST90-1.5T drain outlet — manufactured by McAlpine exclusively for Wetrooms Online, for use with WetBase Linear only. At 83mm deep with a 50mm water seal, it's one of the shallowest wet room drain outlets on the market. Unlike a conventional trap where the waste exits at the base, the CD-ST90-1.5T's exit point sits higher up the outlet body, and a multi-angle knuckle joint between the trap and the waste pipe creates further fall on demand. Combined with 360° rotation of the outlet body, this gives installers the freedom to run the waste pipe in the direction and at the angle the joist layout demands — solvent weld pipe connects directly into the joint, with no separate coupling required. The trap body is rated to a flow rate of 34 L/min, tested under a constant 15mm head of water in accordance with clause 5 of BS EN 274-2:2002. On timber-joisted floors, where shallow joist depth is one of the most common causes of installation problems, this outlet is designed to solve exactly that.

The channel cover is reversible: one side presents a brushed finish in your chosen colour; the other is designed to be tiled over for a near-seamless floor finish. The tray can also be trimmed on site using a handsaw — up to 50mm per side, removing equal amounts from opposite sides to keep the channel central.

💧
Need more flow? Add a second drain outlet
A second McAlpine CD-ST90-1.5T outlet, each rated to 34 L/min, can be added to the channel to double the drainage capacity of your WetBase® Linear — a trusted solution for high-power showers, rainfall shower heads, and any installation where water flow needs to clear quickly. Available as an add-on with this tray.
Timber floor note: The WetBase® Linear tray is 30mm thick. Standard floorboards are approximately 20mm thick, so the tray will typically sit 10mm above the surrounding floor when installed. 10mm tile backer board should be laid over the surrounding floor area to bring it level with the top of the tray before tanking and tiling. The exact thickness required may vary — check before ordering.

Product & Specification
What is a wet room former?
A wet room former, also called a wet room shower tray or floor base, is a factory-made panel that is recessed into the floor structure to create a level-access shower area. It is manufactured with the required drainage fall pre-formed at the point of manufacture, so no on-site screeding is required. The WetBase Linear is constructed from an XPS foam core with a cementitious top coat and is suitable for tiled finishes only.
What is the difference between WetBase Linear and WetBase Standard?
WetBase Standard uses a central point drain, while WetBase Linear features a linear channel drain running across the tray, available in End Drain or Long Side Drain configurations. The waste connection uses the McAlpine CD-ST90-1.5T — a shallow-depth (83mm), 360° rotating drain outlet with a multi-angle knuckle joint, manufactured by McAlpine exclusively for Wetrooms Online for use with WetBase Linear. This gives a cleaner, more contemporary drainage line and is a particular advantage on timber-joisted floors where joist depth is limited.
What sizes are available?
WetBase Linear is available in 10 sizes ranging from 900 x 900mm up to 1700 x 1000mm. Each tray can also be trimmed on site by up to 50mm per side if a precise fit to the shower area is required. Visit wetrooms-online.com/collections/wetbase-linear-wet-room-kit to browse all available sizes, or call 0800 280 8008 for sizing advice.
What drain channel finishes are available?
Twelve matched drain channel finishes are available to complement different tile choices and design schemes, including Flova bronze, aged bronze, gunmetal grey and matt white. The channel cover is reversible - one side accepts standard use, and the other is designed to be tiled over to create a near-seamless floor finish where the drain is barely visible. Maximum tile thickness when using the tileable cover is 10mm.
Is the former pre-formed or do I need to screed?
The drainage fall is built into the WetBase Linear at the point of manufacture - no on-site screeding is required. The XPS foam core and cementitious top coat are non-porous, so the surface is ready to tile over directly without the need for a primer or additional preparation.
Does the kit include the drain?
Yes. Each WetBase Linear kit is supplied complete with a McAlpine CD-ST90-1.5T shallow drain assembly (83mm depth, 50mm water seal), stainless steel grill, and reversible channel cover. A tanking kit to waterproof the joints between the tray and surrounding walls is required but is not included as standard - this is available as an optional add-on when ordering.
The McAlpine CD-ST90-1.5T Shallow Drain
How does the McAlpine CD-ST90-1.5T drain outlet work?
The CD-ST90-1.5T is a shallow-depth outlet at just 83mm, with a 50mm water seal. Rather than exiting at the base of the trap like a conventional drain, the waste exits higher up the outlet body, and a multi-angle knuckle joint between the trap and the waste pipe creates additional fall where it's needed. The whole outlet rotates through 360°, so the waste pipe can be run in any direction to clear joists and other obstructions. Solvent weld pipe connects directly into the joint - no separate coupling is required.
Why is this drain outlet different to a standard shower drain?
On timber-joisted floors, shallow joist depth is one of the most common causes of installation problems - there often isn't enough room below the floor to achieve the fall a conventional drain needs. The CD-ST90-1.5T is manufactured by McAlpine exclusively for Wetrooms Online, for use with WetBase Linear only, specifically to solve this: its higher exit point, multi-angle knuckle joint and 360° rotation combine to create the fall required even where depth is tight. At 83mm deep, it's one of the shallowest wet room drain outlets available.
Can I rotate or reposition the outlet after installation?
The outlet rotates freely through 360° and the knuckle joint can be angled as needed while the waste pipe run is being set up during installation. Once the tray is laid, tanked and tiled, the outlet is not designed to be adjusted further, so the correct direction and angle should be confirmed before the floor is finished.
What is the flow rate of the drain outlet, and is it certified?
The McAlpine CD-ST90-1.5T trap body is rated to a flow rate of 34 L/min, tested under a constant 15mm head of water in accordance with clause 5 of BS EN 274-2:2002 - the European standard for waste fitting performance.
Can I add a second drain outlet?
Yes. A second McAlpine CD-ST90-1.5T outlet, each rated to 34 L/min, can be added to the channel to double the drainage capacity of your WetBase Linear tray - a popular choice for high-power showers and rainfall shower heads where more flow needs to clear quickly. This is available as an add-on with this tray.
Installation
What sub-floors is the WetBase Linear suitable for?
The WetBase Linear is suitable for installation on both timber and concrete sub-floors. It is not suitable for installation directly onto joists - adequate support must be provided beneath the full footprint of the tray in all cases.
What do I need to install the WetBase Linear on a timber floor?
On a timber floor, the floorboards are removed from the tray area and 18mm marine ply panels are fitted between the joists to create a fully supported, even base. Support runners are fixed 18mm down each side of the joists to carry the ply panels. Because the WetBase Linear tray is 30mm thick and standard floorboards are approximately 20mm thick, 10mm tile backer boards are laid over the surrounding floor area to bring it level with the top of the tray. A tanking kit is then applied to all joints and wall connections before tiling.
Can I tile straight onto the WetBase Linear?
Yes. The cementitious top coat is non-porous and ready to tile over directly - no primer is required. A minimum tile thickness of 10mm is recommended. Mosaic tiles or large-format tiles cut to follow the contours of the tray (using an envelope cut) are recommended for best results.
Is the WetBase Linear compatible with underfloor heating?
Yes, the WetBase Linear is compatible with underfloor heating systems.
Can the WetBase Linear be cut to size?
Yes. The tray can be trimmed on site by up to 50mm per side using a handsaw. Equal amounts must be removed from opposite sides - for example, to reduce a dimension by 50mm in total, 25mm should be cut from each opposing side rather than 50mm from one side alone. This keeps the drain channel central within the tray.
Do I need a professional installer?
Wet room installation involves cutting into the floor structure, connecting waste pipework, and applying tanking to waterproof the shower area - work that is typically carried out by a qualified wet room or bathroom installer, or a highly competent DIY'er.
After Installation
What is the guarantee on the WetBase Linear?
The WetBase Linear carries a 20-year manufacturer's guarantee. The guarantee applies when the tray has been installed correctly and strictly in accordance with the supplied fitting instructions.
Does cutting the tray to size affect the guarantee?
Cutting the tray within the permitted limits - up to 50mm from each side, with equal amounts taken from opposing sides - does not void the guarantee, provided the tray is installed in full accordance with the fitting instructions. Cutting beyond these limits or removing material unevenly may affect the guarantee.
Ordering
How do I choose the right size WetBase Linear?
Measure the planned shower area and select the nearest available size from the range of 10 sizes. Bear in mind that the tray can be trimmed by up to 50mm per side on site if a close fit is needed. You should also consider the drain position configuration - End Drain or Long Side Drain - based on where you intend the channel to sit within the shower area. If you need guidance, call 0800 280 8008 and our team will help you choose.
Can I order a custom size?
WetBase Linear is not available in custom sizes. The range covers 10 standard sizes from 900 x 900mm to 1700 x 1000mm, and each tray can be trimmed on site by up to 50mm per side to achieve a closer fit where required.
How quickly will my order arrive?
Orders placed before 2pm are dispatched the same day and typically arrive within 2 working days. Delivery within this timeframe is our aim - it is not a guaranteed service.
