Why a Shower Tray Replacement in Cardiff May Be Needed

Shower trays fail for a few common reasons. Lightweight trays can flex if they were not fully bedded when fitted. Over time, that movement breaks the silicone seal and water gets underneath. Trays also crack, the waste can leak, or the tray may simply be stained and worn beyond cleaning.

Look out for a damp patch or stain on the ceiling below, loose or mouldy silicone, a tray that moves when you stand on it, or a musty smell in the bathroom.

How We Replace a Shower Tray

Carefully remove the shower enclosure and the old tray
Check the floor and the waste pipe for damage
Bed the new tray fully on a solid, level base so it cannot flex
Fit a new waste and test it for leaks
Refit or replace the enclosure and seal everything properly

We can also upgrade to a low-profile tray, a larger tray or a new enclosure at the same time. If the shower valve is old, we can fit a new thermostatic shower valve too.

Shower Tray Replacement in Cardiff: FAQs

How do I know if my shower tray is leaking?

Common signs are a stain on the ceiling below, loose or black silicone, a tray that moves underfoot and a musty smell. We can check and find the source.

Can you replace the tray without replacing the enclosure?

Often, yes, if the enclosure is in good condition and fits the new tray. If not, we can fit a new enclosure at the same time.

Can I just reseal my shower tray instead?

If the tray is solid and the seal has simply worn, resealing may be enough. If the tray flexes or is cracked, new silicone will fail again, so replacement is the lasting fix.

How long does a shower tray replacement take?

Most shower tray replacements are completed in a day. We will confirm timings when we quote.

“We asked Andrey to help us install an outdoor tap. We had restrictions on the dates and he had to work with the company building it. He explained his suggestions very clearly, adapted to the dates we needed and coordinated with the builders. We really trust him and will call him again if we need other jobs.”
