Best way to seal a shower cubicle
Whether you have a shower tray, a shower cubicle, or a shower enclosure, the principle of sealing them is the same.
If you are resealing a shower tray only, then obviously you are only sealing the shower tray itself, whereas with a shower cubicle or a shower enclosure you are probably resealing the shower tray as well as the shower cubicle / enclosure with silicone sealant.
Sealing a shower cubicle or shower enclosure is not difficult, read more below.
Manufacturer’s instructions re sealing a shower cubicle
We’ll assume that you are sealing a new installation for a shower cubicle or an enclosure, or if not, that you have completely removed all of the old silicone sealant. Before the shower cubicle, or enclosure are assembled, you should first of all seal all the way round the shower tray with a proprietary brand of silicone sealant from edge to edge. You are now ready to assemble the cubicle, or shower enclosure according to the manufacturer’s fitting instructions. The main reasons that a shower cubicle, or shower enclosures leak, is because they are often fitted before the shower tray has been sealed, and this means that water can get down behind the channels that are used to secure the shower enclosure, or shower cubicle to the wall tiles. Evidence that it has been fitted incorrectly, will be water escaping from the outside corners onto the floor, or damp patches on the adjoining wall or the ceiling below.
Where to seal a shower cubicle or shower enclosure.
Where should you seal a shower cubicle? – normally you may require a bead of silicone up the length of the channel that is fitted to wall – you do not want to apply alot of sealant to the shower cubicle / enclosure wall channels, as you may require to disassemble it at some point in the future, and if it’s completely stuck the full width of the channel then removing it will be very difficult.
The shower enclosure / cubicle are now fixed to the wall, you now require to seal it, normally on the outside only, along the base, and up the vertical surfaces. Many people apply the silicone sealant to the inside – this is wrong for two reasons: 1) it means that the silicone sealant is constantly subjected to moisture that causes it to go black with mould – if it is applied to the outside, then this scenario does not apply, and your silicone sealant should remain mould free for a prolonged period;
and 2) a shower tray and the shower cubicle, or shower enclosure are generally designed to allow the water to drain back into the shower and away down the plug hole. By sealing the inside you are preventing this from happening, allowing water to be trapped causing leaks out of parts of the shower cubicle or enclosure.
Always follow the manufacturer’s instructions to the letter for sealing a shower cubicle, and if you do that then you are unlikely to have issues, provided that the silicone sealant has been applied correctly. Wrongly applied silicone sealant may lead to leaks that cannot be seen by the naked eye, meaning that the escaping water is causing damage like wet rot etc.
