A Solid Bathtub Is a Lasting Bathtub
There’s nothing worse than stepping into a newly installed bath that feels wobbly, squeaky, or—worse—leaks underneath. At Citywide Plumbers, we don’t just install baths—we secure them. In this guide, we’ll walk you through how to install a bath the right way, so it lasts for decades and feels as stable as stone.
Whether you’re a DIY enthusiast or hiring our expert team, knowing the correct process is key.
Step-by-Step: How to Install a Bathtub (The Right Way)
Prepare the Area Properly
-
Strip old fixtures, tiles, and clear the space.
-
Check walls and floor for damp, rot, or mould.
-
Repair and level the floor if needed.
Citywide Tip: A perfectly level surface is essential—don’t skip it.
Install a Strong Substructure (The Secret to a Rock-Solid Tub)
You can’t just drop the bath in and hope for the best. The base needs solid support.
-
Use a mortar bed or foam support under the tub base to prevent movement.
-
Secure the frame to the wall studs with brackets.
-
Check it’s perfectly level using a spirit level.
We use professional-grade mortar bases for long-term support across all our London installations.
Connect the Plumbing
-
Dry-fit waste and overflow pipes before final fitting.
-
Use quality solvent weld or compression fittings.
-
Ensure watertight connections and proper fall.
If in doubt, let us handle the pipework—we’re fully qualified and insured.
Seal It All Up, Watertight
-
Fit waterproof wall panels or tile the area around the tub.
-
Apply flexible silicone sealant between the tub edge and wall.
-
Allow at least 24 hours before using.
Citywide Plumbers always use anti-mould, high-flex sealants for long-term results.
