Hello . I am up-dating my bathroom . I have ceramic tiling for the floor and a new tolet pan to go fix in . Would you tile the floor first then install the pan . Tiling first avoids cutting tiles around the pan , saving quite a bit of aggravation . Was concerned whether the weight on the tiles doing it this way would make the tiles prone to cracking .Any thoughts would be welcome .
If the floor is made of wood, I would install the pan first. If you lay ceramic tiles first, the wooden floor might 'give' a little, later on, and you could have a cracked tile or two. Even if you can't make a clean joint of tiles around the base of the pan, it can be covered up with sealant.
I suspect the weight of the pan is negligible compared to your weight (no insult intended), so simply walking on the tiles will cause flexing if you have a wooden floor. When standing on one leg, as you do when you walk, the pressure/sq inch will be higher than you sitting on the pan. OG's comment about changing the pan is valid too.
I would cover the floor boards with a sheet material first thus making a level surface and then tile the floor, the even weight of a toilet pan should not then cause the tiles to crack.
But then in the very unlikely-hood that it did you could always replace the cracked tiles.
Thanks everyone . The bathroom floor is actually solid concrete . I think I will go with tiling the floor first . I have a few spare tiles as I bought them in a clearance at my local B & Q . So I will be able to replace any damaged ones as and when .
