Cloakroom Installation in Thurrock | Cloakroom Installation Experts

Thurrock Kitchens and Bathrooms provides cloakroom installation services in Thurrock, from refreshing an existing WC to building a new one under the stairs. A cloakroom has to fit a toilet and basin into a very small space, so every job starts with the headroom, the floor area and how the waste will reach the drains.


That decides the fittings. Short-projection pans and slimline vanity units keep the doorway clear, a stud partition with acoustic insulation forms the room, and moisture-resistant wallboards and metro tile splashbacks protect the walls. Where the soil stack is too far away for a gravity connection, a Saniflo macerator pumps the waste through small-bore pipe instead, provided the house has another toilet on a gravity drain.


Cloakrooms are often windowless, so a core-drilled extractor fan meeting Part F goes in to clear moisture and odours, which matters in damp Thames Estuary air. Most installations take 3 to 5 days under one contract, with a fixed, itemised quote up front.

Cloakroom Installation Services in Thurrock

Under-Stairs Cloakroom Conversions

The space under a staircase is often big enough for a downstairs WC once the headroom is measured properly. Thurrock Kitchens and Bathrooms builds the stud partition around the stair structure, and our plumbers route the water and waste to suit. The toilet goes where the ceiling is highest, so there is room to stand at the basin and the pan.

Short-Projection Toilet Installation

A standard toilet sticks out far enough to block a narrow cloakroom door. Short-projection pans, around 450mm from the wall, give back that clearance and connect to the planned waste route. We pair them with a back-to-wall or close-coupled cistern, depending on the space behind.

Slimline Vanity Basin Fitting

Building Regulations require a basin in or next to any room with a WC, so it has to fit somewhere. Slimline vanity units and corner basins do the job without eating into the floor, with monobloc taps that sit neatly on a narrow ledge. The cabinet underneath hides the pipework and holds spare toilet rolls and soap, and our fitters set it to clear the door swing.

Macerator Waste System Plumbing

Some cloakrooms are simply too far from the soil stack for waste to run downhill. A Saniflo macerator grinds the waste and pumps it through small-bore pipe to the nearest drain, which opens up more of the ground floor for a WC. Building Regulations only permit this where the house also has a toilet on a gravity drain, which we check before recommending one.

Part F Mechanical Extract Ventilation

Most cloakrooms have no window, so mechanical extraction is the only way to clear moisture and smells. A fan rated to the Part F rate of 6 litres per second for a WC is core-drilled through the outside wall. We choose quiet models, as a downstairs WC usually sits next to a hallway or living room.

Metro Tile Splashback Tiling

The wall behind a basin takes splashes every day, so it needs a hard, wipeable finish. Metro tiles are fixed with a flexible tile adhesive and finished with mould-resistant grout, and our tilers plan the courses so no thin slivers appear at the edges. The classic brick pattern suits a small room without making it feel busy.

Cloakroom Installation Process in Thurrock

Step 1: Feasibility Survey and Measurements

Our Thurrock Kitchens and Bathrooms fitter measures the headroom and checks the drop to the soil pipe. That tells us if a gravity connection works or a macerator pump is needed.

Step 2: Studwork Partitioning and Insulation

Timber stud partitions form the cloakroom. Acoustic insulation goes between the studs, followed by moisture-resistant plasterboard ready for finishing.

Step 3: Plumbing and Drainage First-Fix

Waste pipes and water supplies are run to the basin and WC positions. Where a macerator is used, its pipework is connected and pressure-tested.

Step 4: Ventilation and Electrical Hookup

The extractor fan is core-drilled through the outside wall to meet Part F. Lighting and fan wiring are connected and certified under Part P.

Step 5: Tiling, Sanitaryware Fitting, and Testing

Splashback tiles are laid and grouted, then the pan, cistern, basin and taps are fitted. We test the whole system for leaks before handover.

Why Choose Us for Cloakroom Installation in Thurrock?

Thurrock Kitchens and Bathrooms builds cloakrooms around practical engineering and local knowledge. Here is what you get:


  • Specialised Small-Space Engineering: We use ultra-compact 450mm toilets and corner vanity units designed for tight spaces. Dead under-stairs recesses and narrow utility spaces become fully working guest WCs.
  • Thames Estuary Humidity and Odour Control: Your installation features core-drilled, Part F compliant mechanical extractor fans. Stale air and condensation are pulled straight outside, which keeps mould at bay in windowless cloakrooms.
  • Flexible Gravity and Macerator Drainage: We tap directly into external soil stacks or install quiet Saniflo macerator pumps. You gain a convenient ground-floor toilet even when your cloakroom sits far from the main drainage stack.
  • All-Inclusive Fixed Proposals: Your written quote itemises all carpentry, plumbing, electrical connections, and sanitaryware costs before work begins. The price is fixed for the agreed scope, with no add-ons once the job starts.

How Much Does a Cloakroom Installation Cost in Thurrock?

The cost of a cloakroom from Thurrock Kitchens and Bathrooms depends on the scope. Swapping the toilet and basin in an existing WC costs far less than a new under-stairs conversion, which needs stud walls, new water supplies and a connection to the drains.

Frequently Asked Questions About Cloakroom Installation in Thurrock

What is the smallest space Thurrock Kitchens and Bathrooms fits a cloakroom into?

We usually need at least 800mm by 1400mm, which fits a short-projection pan and a compact basin with room to use them.

How long does a cloakroom installation with Thurrock Kitchens and Bathrooms take?

Most of our cloakroom installations take 3 to 5 days, depending on the drainage and electrical work involved.

Do I need planning permission for a cloakroom in my Thurrock home?

Usually not, as a cloakroom is an internal alteration. The work does need to meet Building Regulations for drainage, ventilation and electrics, which we handle for you.

What drainage options do you use when there is no nearby soil pipe?

We fit a Saniflo macerator that pumps the waste through small-bore pipe to the nearest drain. Building Regulations permit this where the house also has a toilet on a gravity drain.

Does Thurrock Kitchens and Bathrooms handle the electrical work?

Yes. Our electricians wire the extractor fan and lighting and certify the work under Part P of the Building Regulations.

Will Thurrock Kitchens and Bathrooms convert an under-stairs cupboard into a cloakroom?

Yes, in many Thurrock homes. The cupboard needs at least the 800mm by 1400mm footprint, enough headroom at the toilet end and a route for an extractor fan.
