DIYer here doing my first curbless shower install and looking for advice on floor prep.
1. Adjoining rooms to bathroom are 3/4” nailed hardwood.
2. Subfloor is 3/4” OSB on I-joists 24” on center.
3. I plan to lower the shower floor area by 3/4” to be even with top of joists. Shower floor will need to be a custom dry pak mud due to a triangular area. I might use a Schluter preformed pan and dry pak around it.
4. I’d like to try a linear drain with it parallel to the shower door and close to it so that water will hit the drain and not get into bath area. With about 4-5’ length and 1/4” slope per foot the pan height would be 1-1.25”.
5. Shiould I use 3/8” porcelain tile for best water resistance for shower and bath? Or a different thickness?
6. I have 1/2” Hardiebacker boards on hand and Schluter Ditra mat. What do I add on top of the bath subfloor to make the transition from bath to shower area work right? I suppose using the Ditra and Kerri is the best for underneath tile for water protection. I am not sure what to use below the Ditra layer considering the shower pan height and the adjacent hardwood flooring and not too big of a transition. I think I will use a marble threshold in the doorways as I can’t think wood/tile will be ‘clean’.
Sorry for the lengthy post… I think I covered everything I’m dealing with.
Thanks in advance!!!
