My acrylic bath has developed a crack about 3 inches on the shiny surface inside the bath!  It dosn't appear to be leaking, but I fear it's only a matter of time! 

Can it be fixed? Maybe with some sort of epoxy resin or gelcoat? I was wondering about running a soldering iron down the crack, which wouldn't be pretty but might seal it for a while.... 

Any advice appreciated as always!!

I reckon you could probably do a fiberglass patch but I won't look very good unless you can match the colour well.

I've got an old cast iron bath doing nothing if you want a replacement.

It weighs about the same as The Titanic.

Dont let the pikey's know that 

Fiberglass it from underneath

But probably floats better

That's what I would do......

If the crack is just in the gel coat layer, drill a tiny hole just through the very surface at each end of the crack to stop it spreading any further. You might then be able to gouge out the rest of the crack and fill with an appropriate coloured gel coat, cover with cling film and let it set, then some 1000 grit wet and dry, finishing off with G3 or something. Depends if you can find gel coat to match the colour of the surface exactly.

More importantly, why is it cracking......its often due to the chipboard support under the fibreglass/gelcoat either disintegarting due to water ingress or the bath not being square, level and fully supported by all the supporting feet.

...or it's just a crap bath. Our old one, fitted when the house was built, used to creak and flex, with very small cracks in the base visible when we moved in. The under side fixings and floor boards where solid.

Re fitted Bathroom time came round, and used a carronite bath. Although its more expensive, It's rock solid, with no flexing at all, so allows the bath to stay fixed solid and not flex the mastic seal.

you can get an acrylic repair kit,but it depends what colour you bath is tho.

Chipboard support pretty much fell off the cheapy bath the previous owners fitted in my house.. so the whole lot is now wedged up with wood under the complete underside. At least it doesn't bounce up & down as I get in now..

i will never buy a bath or fit it if the board isnt also fibre glassed,also having the adjusting feet tightened correctly and bath fitted correctly helps
