The best offset shower tray depends on whether you need a ready-made tray or a tile-ready base for a custom shower. The five options below include linear offset trays and a slimline offset tray; most are not explicitly identified as quadrant-shaped, so check the shape, dimensions, drain position, and handing before ordering. Showertec offers concrete bases with drain markings, while Schluter provides lightweight trays with integrated waterproofing.
| Product | Best For | Listed Size |
|---|---|---|
| Showertec STL-TRAY132/112 | Larger tile-ready shower bases | 52 x 44 inches |
| Showertec STL-TRAY91/112 | Compact tile-ready shower bases | 36 x 44 inches |
| VeeBath Slate Grey RH | Slimline wet-room installations | 900 x 800 mm in name |
| Schluter KSLT1220S | Lightweight, tile-ready installation | 48 x 48 inches |
| Schluter KSLT1395S | Larger tile-ready shower layouts | 55 x 55 inches |
Showertec STL-TRAY132/112 52 x 44-Inch Tray
This large-format linear offset base is best for buyers planning a tiled shower who want a reinforced concrete foundation. Its listed size is 52 by 44 inches, making it the larger of the two Showertec options in this selection.
The fiber-reinforced concrete is described as supporting durability and adhesive grip for tile. The tray also provides waterproof protection and has pre-cut drain markings that can be customized for alignment with linear or point drain systems. Those markings offer flexibility, but the installer still needs to confirm the drain location against the plumbing plan.
Choose this if you need a broad tile-ready base and want marked options for drain placement. Limitation: it is a substantial-format tray, so confirm the available floor area and intended installation dimensions before purchase.
Showertec STL-TRAY91/112 36 x 44-Inch Tray
This smaller Showertec model is best for a more compact shower footprint that still needs a tile-ready base. Its listed dimensions are 36 by 44 inches, narrower than the 52-by-44-inch Showertec model.
Like its larger counterpart, it uses fiber-reinforced concrete, includes waterproof protection, and has pre-cut drain markings for adapting the drain opening to a linear or point drain system. The reinforced material is intended to support tile adhesion and a stable foundation.
Better for buyers whose layout needs the narrower footprint while retaining the same stated material and drain-marking features. Limitation: the product information does not specify a quadrant shape; verify the tray’s outline and drain position for your enclosure.
VeeBath 40mm Slate Grey RH Offset Tray
This VeeBath tray is best for shoppers considering a slimline base for a walk-in wet-room enclosure. The listing describes Pearlstone Matrix construction and a height of 40–45 mm, presenting the tray as a low-profile option. It is identified as right-hand (RH) in the product name.
The listed material is described as strong and lightweight. However, the supplied product details conflict: the name gives a 900-by-800-mm size and slate-grey finish, while the feature text lists different dimensions and says the color is white. Verify the exact size, color, and right-hand orientation with the seller before ordering. This mismatch makes the listing less straightforward to compare than the other options.
Schluter KSLT1220S 48 x 48-Inch Tray
This Schluter tray is best for buyers seeking a lightweight, tile-ready shower base with integrated waterproofing. The listed dimensions are 48 by 48 inches. Its expanded-polystyrene construction is described as supporting quicker installation and curbless shower setups.
The KERDI waterproofing is integrated, and the tray is designed to slope toward a KERDI-LINE drain. The product information also notes compatibility with large-tile design approaches. Choose this if a lightweight base and integrated waterproofing are priorities for your planned installation.
Limitation: the specified drain system is part of the design, so confirm that the tray and intended drain arrangement suit your project before purchase.
Schluter KSLT1395S 55 x 55-Inch Tray
This larger Schluter option is best for shower layouts that can accommodate a 55-by-55-inch tray and use a tiled finish. It shares the KERDI waterproofing and lightweight expanded-polystyrene construction described for the smaller Schluter model.
The tray is designed to slope toward KERDI-LINE and supports design flexibility with large tiles. Compared with the 48-by-48-inch KSLT1220S, this model offers a larger listed footprint, so it may suit projects with more available floor space.
Limitation: its larger dimensions require careful planning, and the product details do not identify it as a quadrant-shaped tray. Check the layout and drain requirements before selecting it.
Buying Guide: How to Choose an Offset Shower Tray
Does the tray need to be quadrant-shaped?
“Offset” can refer to a drain position, an asymmetrical tray shape, or a particular enclosure layout. These product listings mainly describe linear offset or wet-room trays and do not consistently confirm a quadrant outline. Match the tray shape to the enclosure drawing rather than relying on the keyword alone.
Which size and drain position will fit?
Measure the available shower footprint and compare it with the product’s stated dimensions. Confirm drain location, drain type, and plumbing alignment before buying. Showertec lists pre-cut drain markings for adapting an opening, while the Schluter trays are described as sloping toward KERDI-LINE.
Should you choose a tiled base or a finished tray?
A tile-ready base is suitable for a tiled design, but installation details and waterproofing still matter. Showertec lists a concrete base with waterproof protection; Schluter lists integrated KERDI waterproofing. The VeeBath listing describes a slimline tray, but its size and color details should be verified.
What should you verify before ordering?
- Exact tray dimensions and shape.
- Left- or right-hand orientation, when applicable.
- Drain location and required drain system.
- Whether the product is intended for a tiled finish or a finished surface.
- Conflicting listing details, especially for the VeeBath model.
Frequently Asked Questions
Are these all quadrant shower trays?
No. The supplied descriptions identify linear offset and wet-room products, but do not confirm that every tray has a quadrant shape. Verify the outline before purchase.
What is the difference between the two Showertec trays?
The listed sizes differ: the STL-TRAY132/112 is 52 by 44 inches, while the STL-TRAY91/112 is 36 by 44 inches. Both list reinforced concrete, waterproof protection, and pre-cut drain markings.
Which options include integrated waterproofing?
The Schluter KSLT1220S and KSLT1395S listings specify integrated KERDI waterproofing. Showertec separately describes waterproof protection in its product features.
Is the VeeBath tray definitely slate grey and 900 by 800 mm?
The product name says slate grey and 900 by 800 mm, but the feature text gives conflicting color and dimension details. Confirm the exact specifications with the seller.
