What are toilet units?
A toilet unit, also known as a WC unit, combines a back to wall toilet pan with a furniture cabinet that conceals the cistern and plumbing connections. Unlike standard toilets with exposed cisterns, these back to wall toilet and cistern units hide all mechanical components within the cabinet structure, creating clean, minimalist aesthetics with no visible pipes or tanks.
This integrated approach delivers three key benefits: streamlined appearances, easier cleaning around the toilet area, and coordinated furniture aesthetics when paired with matching vanity units.
WC toilet unit sizes
Our collection offers three width options suited to different bathroom layouts:
-
500mm WC Units: The most compact design, perfect for small bathrooms, cloakrooms, or where space conservation proves critical.
-
540mm WC Units: Mid-width option offering slightly more surface area and internal storage volume whilst maintaining compact footprints suitable for most bathrooms.
-
550mm WC Units: Our most popular width, providing generous surface space and optimal proportions that suit standard bathroom layouts.
All units feature cabinet depths of 200mm-299mm, with total projection, including the toilet pan, typically 700mm-899mm depending on pan selection. Heights range from 800mm-899mm, creating comfortable working surfaces.

Which WC unit style should I choose?
Choose between contemporary and classic design approaches. Modern WC units offer clean-lined designs featuring smooth faces, handleless profiles, or minimalist hardware. Whereas traditional WC units feature raised-panel doors, detailed mouldings, and classic proportions. These coordinate beautifully with traditional bathroom furniture and heritage-style fixtures.
Or you could choose a fluted WC unit. Our premium Evora range features vertical groove detailing adding dimensional texture and contemporary character. The linear fluting creates visual interest whilst maintaining clean, modern profiles. Explore fluted bathroom furniture for coordinated pieces.
Toilet unit colours and finishes
Transform your bathroom with diverse finish selections across modern and traditional aesthetics:
-
White Toilet Units: Gloss white finishes create fresh, clean backdrops that brighten compact bathrooms. The reflective surfaces pair effortlessly with any colour scheme whilst maintaining timeless appeal.
-
Black Toilet Units: Matte and gloss black options deliver contemporary drama. Choose from obsidian black, hale black, or matt nocturne black for sophisticated modern schemes that coordinate with black bathroom furniture.
-
Grey Toilet Units: Versatile grey tones including indigo grey gloss, pebble grey, and graphite grey offer neutral sophistication suited to both warm and cool colour palettes.
-
Green Toilet Units: Contemporary green hues from soft mint sage to deep moss green bring natural calm and botanical character. Perfect for creating spa-like sanctuaries or nature-inspired schemes.

Personalise your toilet unit with accent trims including classic chrome, matt black or brushed brass. These allow you to coordinate handles with taps and shower fixtures. Select WC units offer multiple accent trim options for the same cabinet colour, allowing you to customise hardware to match your bathroom fixtures precisely.
Browse coordinating bathroom furniture for unified schemes.
Coordinating WC units with vanity units
Create unified bathroom furniture schemes by pairing WC units with matching vanity units:
Most WC units belong to larger furniture collections offering coordinating bathroom vanity units in identical finishes. Even across different ranges, matching colours and materials create cohesive aesthetics. Pair gloss white WC units with white bathroom furniture, or coordinate green tones with green bathroom furniture. To coordinate colours, select matching accent trims across WC units and vanity units for unified metalwork throughout your bathroom.
For compact schemes, explore cloakroom vanity units or combination vanity units for space-efficient solutions. For coordinated bathroom suites combining toilets and basins, explore our range of toilet basin suites.
Installation considerations for WC toilet units
Installing WC units requires careful planning around waste connections (typically a horizontal outlet 180mm from finished floor level), concealed cistern water supply routing, and strong wall fixings to support the combined weight of the unit and user. Floors should be level to ensure proper flushing, with adjustable feet used where available, and a minimum of 600mm clearance in front of the toilet is recommended for comfortable use and easy cleaning access.
For detailed guidance, consult our installation guide for WC units and bathroom furniture buying guide.
How to maintain and clean a WC toilet unit
Keep your toilet unit looking its best with simple regular care: wipe surfaces daily with a damp cloth, clean the bowl weekly using standard toilet cleaner, and use mild products on cabinet exteriors to avoid scratching finishes. Periodically check the concealed cistern via the access panel to inspect flush mechanisms and replace worn parts as needed, and lightly lubricate soft-close seat hinges if they become sticky, avoiding forcing the seat closed to prevent damage.
