Repairs and problems
Gaps appearing along the bath or worktop seal
What actually fixes it
- 1
Sealing an empty bath creates a joint that tears the first time it is used with someone in it.
- 2
A gap at one end only usually means movement or an unsupported bath rather than sealant failure.
Before you commit
Sealing an empty bath creates a joint that tears the first time it is used with someone in it.


Your questions answered
Can I seal over the gap?
New silicone will not bond well to old; the joint should be cut out and redone.
Should the bath be supported more?
Additional leg support and a battened edge reduce movement and extend seal life.
Add sealant gaps to a wider project?
Plenty of this work happens alongside other jobs in the house. Tell us the whole picture and the sequencing gets easier.
