How To Fit A Walk-In Shower Tray — Trade Method
How to fit a walk-in shower tray is a manageable job for a competent DIYer with basic plumbing tools — provided water is isolated and joints pressure-tested. Here is the exact sequence UK plumbers follow.
Step-by-step method
1. Prepare and isolate
Adjustable spanner, PTFE tape, silicone grease, cloth, bucket. Isolate water. Prove zero pressure.
2. Remove old
Photograph existing setup — pipe orientation, sizes, sealant type. Save time on reassembly.
3. Prep pipework
Cut square, deburr, clean copper to bright. Plastic pipe needs stiffener for push-fit or compression.
4. Fit new component
Follow torque instructions. Overtightening splits olives. PTFE 5 wraps clockwise; jointing compound on BSP taper.
5. Pressure-test
Restore slowly to purge air. Check joints with dry tissue. 30-min pressure hold; recheck under thermal cycle.
Frequently asked questions
Building regs?+
Most domestic plumbing is non-notifiable. Gas, unvented, full CH require registered installer.

Olive not seated, PTFE wrong direction, or nut needs 1/4 turn more. Off, reseat, retest.
