Bath to large shower conversion

If the old bath is set down (recessed) into the slab you may have a good base for a new walk in shower.

If on the other hand the slab is flat under the bath you can end up with just a 25 to 30mm step at the entrance.

The small window will also need to be waterproofed.

Location of the floor waste into the old bath outlet will be no problem provided yo can give the some fall.

Rather than a prefabricated, have you looked at getting the base waterproofed and shoer water stops installed? this will outlast a prefab base and look a lot netter and easier to keep clean.

Good luck.

The bath wasn't on a slab, it was merely fitted in a cut out wooden floor and built-in that way.So When the bath is pulled out it will be open to ground below and will need to have the floor patched up or the whole bathroom floor replaced.

Being above ground you will also have to waterproof the whole floor and install puddle flanges.

Although I really like your idea of getting the base waterproofed and having shower stops, it sounds difficult and expensive to have done professionally. Would you have any idea of the cost for my job? I am in near Melbourne airport, in the north, and it looks like there is only a contractor in the Western suburbs.

I have also read that walk in showers are very to difficult to DIY and I don't like tiles. I am going to do the walls with shower wall panels and the floor with aqua-step, as they are supposed to be waterproof.
Thanks again.

Discuss this with the waterproofer doing the quote, he can also waterproof your prefab base.

Good luck.

Sounds a lot like the bathroom renovation we just finished. We deleted the window altogether and don't miss it at all. A powerful fan helps with ventilation.
