The two floor is made of channel steel barrier, but also want to do a toilet, just sitting and washbasin, so that the bathroom floor tiles can be it? What special treatment do you need? Ask designer friends for advice
The wall board is very troublesome, first is waterproof and load-bearing problems (wall tiles), wood best brush a layer of insulation waterproof soft waterproof glue, then construction
The structure of the ground to do a layer of cast-in-place (seven or eight cm thick, then can) make a layer of mortar cushion (leveling), then protect the water again (best done 2 times, prevention), construction finally late (tile etc.)
It is best not to do the toilet (for short periods of time can be), a long time after their own great wall tiles falling force, the board will damp, future risks are great (unless you do a few times waterproof layer and a reinforcement layer, but the price is too high, you can consider the use of red brick walls)
Yes, of course. It can be made of bricks, but it depends on your water resistance. Waterproof, please professional waterproof team. For blocks, please use small pieces
Do you can do is take the above channel, big core board, cement board and cover, the above can be waterproof, OK, or a steel plate surface anti slip can be waterproof, of course you can also consider tiling; what type of channel, the sewer pipe should not drain what problem that is how the toilet water row, if water is straight then you do not need to consider this question.
