Browse Forums Bathrooms and Laundry 1 Jun 15, 2010 3:10 pm My builder has laid the orange tongue on the ground and 1st floor and my instructions were to have walk in showers (3 of them) meaning flush tiles for the shower meeting with the floor. My builder (very good but old fashioned) wants to build up the shower so I will have a slight raise to the showers. This is not what I want, nobody has showers like that anymore for custom built houses. Apparently you have to drop the floor? My builder does not want to do this, he says it will destabilize the area. What should I do? Re: problem with builder over shower floor 2Jun 15, 2010 6:15 pm What are you building on - I guess a concrete slab? We are in the process of renovating a unit; the bathroom is already done. The original bathroom had a "skin slab" on the floor, so there was a step up of approx 4cm as you entered the bathroom. I believe this was a popular way of ensuring the bathroom had plenty of fall in the floor, for drainage. We wished to eliminate the step up, so after removing the skin slab our tiler simply added concrete shaping to the floor instead. I believe another way is to grind the slab away to assist with achieving greater fall, but I personally don't know anyone who has done this. Good luck! I would definitely look for options other than a skin slab, anyway. Re: problem with builder over shower floor 3Jun 16, 2010 4:15 pm No the floor is on timber not concrete and thats the problem, he will not cut into the floor pozzies because he reckons it will destabilize the floor. This is a new house not a reno. Re: problem with builder over shower floor 4Jun 16, 2010 4:36 pm Quote: . My builder (very good but old fashioned) wants to build up the shower so I will have a slight raise to the showers. This is not what I want, nobody has showers like that anymore for custom built houses. If you have used something like a posi-strut for your floor joists, then you can't really cut into them. If you have used solid timber joists, you may be able to check them out to get the fall. That being said, it's actually not uncommon to do what he is saying. The method he is talking about is used quite often in this situation, especially in renovations (but also in new builds as I have seen it used in new townhouses). Basically you screed the whole bathroom floor up to the shower area, which therefore creates a raised floor around the shower, which you can then fall into a drain. This process creates the stepless shwoer base. The carpet that joins the bathroom however has to be ramped up to meet the raised height of the bathroom floor. One method is to use something like an mdf "wedge" and lay the carpet onto it. The other, probably more common method is to use a self levelling screed (ardit) and ramp the carpet up to meet the bathroom floor. You do notice the carpet ramping up, but you don't notice the bathroom floor height so much.
