Options to consider in Knowle

Full wet room

The entire floor is tanked and falls gently to a single drain, often a linear channel near the wall. It's the most open, step-free layout and the easiest to clean. A fixed glass screen keeps spray off the toilet and basin, and the floor tiles need good slip resistance when wet.

Accessible wet room

Designed for wheelchair users or people with limited mobility: a wider door if needed, grab rails fixed into reinforced walls, a fold-down seat, a thermostatic shower, a comfort-height toilet and lever taps. Work like this can sometimes be funded by a council Disabled Facilities Grant, and it may qualify for VAT relief.

How much should you budget in Knowle?

Expect to budget between £5,000 and £15,000 depending on size and specification in Knowle. Converting a 2 m × 2.5 m bathroom into a fully tanked wet room with a level-access floor: typically £6,800–£9,000.

Wet rooms in Knowle: common questions

How much does a wet room cost?

In the West Midlands, wet rooms typically cost £5,000–£15,000, including VAT where it applies. Converting a 2 m × 2.5 m bathroom into a fully tanked wet room with a level-access floor usually costs £6,800–£9,000.

Which postcodes in Knowle do you work in?

We cover B93 and the streets around them. If you're on the edge of Knowle, neighbouring Dorridge and Balsall Common are covered too.

Are wet room floors slippery?

They don't have to be. We use floor tiles with a slip-resistance rating suited to wet barefoot areas, and smaller tiles in the shower zone give more grout lines for grip and follow the falls better. A fixed screen keeps most spray in the shower area. Grab rails and a seat add security for anyone unsteady on their feet.

Does Solihull Council need to approve my wet room?

You won't usually need planning permission, but the work must meet Building Regulations. Building control in Knowle is provided by Solihull Council or a registered building control approver, and some work is self-certified by registered installers.
