Bath won't stay sealed

sarahevie

Had a new bath fitted four years ago.

It has needed resealing fairly frequently snce. As after a cuple of months the bath 'sinks' leaving a gap beween the bath and tiles.

In Feb this year we hired a local plumber who said it had been incorrectly fitted. So battoned plywood underneath to keep it in place. However, three months on the seal is starting to lift away from the bath again.

Scraper it all off, fill the bath with water and re-seal it, this time, warm the sealant in a bowl of hot water before use, dry the tube and go round with warm sealant , leave the water in the bath until the sealant has fully cured

He was correct.

Did he remove the bath first, fix battens, refit and solidly secure bath?

Oh no I see he didn't. Needs doing again but properly this time - sorry. Proper treewood battens too - using ply is a joke.

Cheers

Bath should be removed along with old silicon.
Either batten the 2 or 3 walls the bath fits along, or build a cage for it to sit on if space allows.
Refit the bath, but use a tube of silicon or plastic window frame sealant to secure it to the wall(s). Allow this to go off (24hrs).
Fill bath with water (to just under the overflow).
Ensure that the bath and wall are completely dry along the sections to be siliconed, then apply a good quality silicon such as Plumbers Gold. Then allow this to cure for 24hrs befor draining the water out.

This method has never let me down and I've fitted too many baths to remember exactly how many. (Blimey, I feel old thinking about it).

Good luck

If the plumber did a poor job, could you give him a bell and ask him to do it properly?

You need some of that edging that fits under the last set of tiles and then has a flexible 'lip' which goes over the silicon bead. All done with the bath half-full

Think you may have misunderstood the question.

If the edge of the bath that fits against the wall is not sitting on a frame or a batten you have very little chance of preventing the problem from re-occurring.

If the bath is cheap thin plastic you are wasting time and money as it will always flex.

Either replace the bath with one made of thick plastic (not cheap) or enamelled steel (cheap).
