Hello: Hubby and I were talking about our 2 bathrooms and whether or not we could update them. He's REALLY handy - plumbing, electrical, etc. We've finished two basements and we're still married! Our house is about 25 years old and both bathrooms are clean but dated. One has a tub/shower, tiled with 6" x 6" tiles on the walls and ceiling of the tub area as well as going out and half-way up the 3 walls around the toilet. The other bathroom has a shower stall with the same 6" x 6" tiles and 1" x 1" tiles on the floor of the shower. No problem for us to do new cabinets (sinks and taps are fine) but how easy is it to put in one of those 'bathfitter' units? The tub is actually OK - it's the tiles we would like to cover. We live in the country and have hard water softened with a water softener (hence, calcium, lime, salt and a bit of mildew). We would really like to avoid taking out all that tile (we did it in the first house and it wasn't fun ) and simply put the new unit in over it. I know we would have to kill the mildew before covering it but ... is it something we should even consider doing ourselves? Has anyone done this?
