wet area and habitable area level the same height

[strive and prosper]

Can someone please advise I am building a new house and in our contract I included that the level of the wet areas and the habitable areas are to be the same. Our supervisor has told me they cannot alter the level of the slab in the wet areas as it is not in the engineers drawing and we will have to raise the level of the habitable floor areas to create the same level.This is a large area and obviously will cost us as we are doing it after handover. In my previous house we lowered the level in the wet areas when the slab was poured this enabled the fall to drain being achieved and the level flowed throughout the ground floor.
Any advise or suggestions would e appreciated.

Your builder has to deliver what's written in the contract. End of story. The builder suggesting that the finished floor level of the rest of the house has to be raised is a) stupid beyond belief and b) something that the builder would have to do at his expense not yours.

That being said, if by some chance there is fall to the wastes built into the concrete slab in the wet areas, then you should be able to tile them without installing a screed.

Thanks for your prompt reply i will have to speak to the supervisor again as they are pouring the slab this week it will be difficult as it is a project building company. We do not want a step up to the wet areas so I will see what he says this time.The problem is the building company is not tiling the habitable area only the wet areas.But as I said it is noted in the contract

BIG call trusting the conctreters to get the falls right in the wet areas... I would NEVER trust them to do this right ever! Stepping down to achieve what you want shouldn't be a problem & would result in the builder using less concrete & less care as to the finish in the wet areas, so not sure why he would be hesitant?

That's why I said "If by some chance...."

The issue with the recessed wet area floor is the engineering. The concrete thickness and the beam locations have to be taken into account, which is what the supervisor was saying.

Why wont you just settle for the wet area floors to be raised and leave the rest of the house as is???....

Thanks for the responses apparently it has been now rectified I just have not been informed as yet what option has been accepted. The reason we want the floors to be one level so you dont trip up the step and also no private builders homes we have viewed, have a step up in their wet areas on a new building.

Another way to elliminate a trip hazard is instead of having a 40mm angle at the wet area doors- have the tilers install a ramp instead. The width of the ramp will be the same as the width of the door frame. Generally for lowset homes, we only screed inside the shower recess with a hob and straight stick the rest of the floor. This should be ok as most of the water is retained in the shower anyway.

Thanks again for all your replies it has been rectified they are reducing the level of the slab in the wet areas by 30mm all good.

I haven't seen a hob in years ttek.... everyone wants their showers to "flow" through these days...heaps are going for only a half shower screen or none at all to. It really tests out your screeding skills to get the falls right, with no water escaping the shower area, especially when they want a large format tile to boot.
I have done plenty of jobs where the original slab is set down to allow for us to install our mortar bed. It's a good look.
