    minimum 10cm lower for bathroom floor?

    hi

    as i understand it, most thai architects/contractors recommend 10 cm lower for bathroom floors and maybe also for the patio outside.

    i was wondering whether it would be sufficient to just do 1:200 sloping to contain the spread of water. if this is not possible, i would like to lower the floor by a minimum in combination with a slope of 1:200

    i would like to enquire whether 1-2 cm lower in combination with a 1:200 slope would be sufficient.

    thanks

    I have just started work on my bathroom and I was unsure what to do, only by preference mind.

    As I've moved the shower down to the far end of the room, from its original position of the centre, i decided to make the bathroom floor level, and the shower area sloped. Half and half so to speak.

    I think the sloping you have suggested shouldn't be a problem providing you use smooth tiles (None slip type) and not the slate ones that can hold surface water.
    You bullied, you laughed, you lied, you lost!

    I used Bathroom tiles in the bathrooms so they are not slick, and level floors with a 12 cm curb and partial wall head hight for a shower in the back half with toilet and face bowl and mirror in the front half.
    same as in the west, at least in America.
    That way the floors are dry and not slick and if we or someone comes to visit wearing socks needs to use the bathroom can do so instead of pissing theit pants or haveing wet socks and feet.
    I would not have wet floors in my home.

    Just because it is don't thru lack of intelligence in a 3rd world country does not mean it is the right way.

    The drop that is recommended is fine for Thai bathrooms where water gets thrown around a lot, but hardly necessary if you have a shower in a corner

    I actually like the idea of a well being created so that the floor can be washed down without spilling out, but it is up to you how big a drop, if any

    A level floor with the slope around the shower works for me, as long as the slope is carefully done - it can be a pain if the slope does not contain the water as you shower
    I have reported your post

    I would go for more of a slope than 1:200.

    just built a house in Sukhothai and we have a level (1:200) floor no problems with water flooding out the door as we have the shower at the far end of the room. it took a lot of "discussion" to get the builder to not drop the floor 50mm.
    don't forget to put in a "U" bend or the stink will from the stagnant water.

    We have a very slight slope in the shower, but it was Thai did the work, so who the fuck knows, I tld them to make floors level in the whole house, so if I dumped a bucket of water it would not pool anywhere, might as well have told them to make it moon shaped, as the kirchen/diningroom floor is 5 cm lower in one corner where the table sets than it is anywhere else, it rained and blew in before we had the windows in and it looked like an indoor pool in the fucking dining room.

    But you know the Thai Mantra="Close enough is Good enough"

    I can relate to the above problems of sloping concrete floors. I recently started my house build in Issan, but I wanted the outdoor kitchen to have a sloping floor with the drainage point in the middle of the room. After telling the wife many times that the builder must slope the floor towards the drainage hole, we left to go shopping.
    After the slab had dried next day, I decided to test the floor .
    Guess what! the bloody water goes everwhere but towards the drainage hole.
    After that effort, the builder was kicked off the property and told never to set foot on there again.
    My fault , probably, for hiring the local village buider( or was that the village idiot!)

    ^ we were lucky with our builder. I too wanted the same but the drain ended up in the middle of the room but near the wall. It works perfectly though, and probably looks better too so I let him off.

    We used one of these new disguised drains from Cotto.

    In fact I think I will do a bathroom thread when I have finished grouting today.

    If the floor was going to be tiled why did you waste your time testing the slab slope?

    Also drains really do need to be near a wall, as the tiles need to be sloped with it being near the wall(preferably a corner) that is one(two) less direction for the sloping, in the center and you need 4 different slopes, the tiling will look crap.

    I was wondering that too!

    most builders will lay the slab floor more or less level then make the tiles slope in the direction you want

    maybe you should apologise to the builder, backinpd?

    This would be the best solution in the Farang world. Unfortunately most of the (local) Thai builders cannot build a correct slope.

    So the lower bathroom floor is not «nice» and «elegant» for us Farangs - but it is the safest way not to swamp your other rooms. It also avoids the endless discussions, misunderstandings etc. with you builder...

    as was said ages ago, the step into bathrooms is mainly for the traditional bathrooms where you throw water about with gay abandon from a tub

    if you have a shower it is hardly necessary. I have had eight (yes, 8) bathrooms built with sloping tiled floors and all work very well

    incidentally, I have also built three wet rooms in Europe; one of those does not work well as the slope is not correct...an English builder did that

    I almost finished the bathroom yesterday, the builders went back in yesterday evening after I finished and they cracked a tile! Now that will have to be replaced.

    Just the fittings to put up and the tile to be replaced and we are done I think.

    Sorry - "no rubbish" - this is my experience (2008-2010) in Hua Hin...

    The best solution to me is still the outdoor shower.

    Outdoor showers are cool.

    If I build a house from scratch here I will be having an outdoor shower for the en-suite bathroom.

    I stayed at a nice resort near Jakarta once (1000 islands); they had outdoor showers and were very good for sex

    I have one in our house in Hua Hin. Our master bathroom has only this outdoor shower. This keeps all the humidity out of the bathroom.

    And it is a great feeling taking a shower under the open sky...
