Hello Lisa, I would suggest this would be approx between £60 - £120. Decent sealant costs approx £6 - £12 a tube, and insist on the anti-mould kind that resists black growth & mould, some are guaranteed for 10yrs plus. Also make sure the tradesman fills the bath with water before he seals it to stop the sealant splitting. ( you would be surprised how many tradesmen don't do this simple job right ). Bath panel, is it to be made from scratch? or do you have the plastic kind? Kind regards Steve
