Curbless shower questions and decisions
Comments (57)I have a very similar design happening, large format tiles, curbless with trench drain, floating vanity etc. I am very close to the glass install. Curious about your glass install. How is it secured so that it does not wobble? Floor to ceiling, wall brace, or? I am considering a panel about 72" high by 54" long, the length of the shower, fixed to the wall and secured to the floor without screws because of danger of puncturing membrane. Panel would be stabilized by a return panel 8-12" across the shower opening. We were going to try it first without a door. Thanks....See MoreBasic Curbless shower - linear drain - what it looks like?
Comments (7)"So there has to be space for a "pool" somewhere around the drain whether you use a center regular drain or a linear drain." Yes. No matter what your design, or what type of drain you install, there are pretty much two basic requirements: 1) the shower floor area needs to be sloped towards the drain at a min pitch of 1/4" per foot and a max of 1/2" per foot. 2) With the drain plugged and with a 2" standing depth of water over the drain, waterproofing needs to contain the pooled water from intruding in to the non-waterproofed areas of the house. "In the diagram I included above, if the linear drain were recessed to meet the 1/4 inch per foot of run, then it would be okay but that gets us back to seeing that a linear drain requires being recessed just like a regular drain. " Correct. For your depiction above with no changes to the drain elevation, let's say you install the drain "as is". The floor to the right of the drain that is in the shower would need to pitch to the drain at 1/4" per foot, so the floor tile at the right wall would be elevated 1-1/8" (4.5' times 1/4" per foot) above the drain. If the bathroom floor to the left of the drain was flat (as it is in the drawing), you'd have to install a 2" vertical curb at the bathroom doorway. Your wall-mounted toilet and vanity protect those items. You'd then have to waterproof the entire floor and run the waterproofing detail up the walls several inches. Let's say you want to keep your bathroom floor flat with no curb at the bathroom/bedroom door threshold. Here are a couple of examples of how you could account for the required 2" vertical. In new construction they are easy to accomplish, in remodeling maybe not so easy: 1) drop the floor in the shower 2" below the bathroom floor by shaving down or dropping the floor joists. Then reverse the direction of the floor slope in your shower so it slopes down from left-to-right. Your trench drain will now be at the right wall. With your bathroom floor "flat", you'll have a curbless entry at the bathroom/shower floor transition. The shower floor will slope down to the drain at a little under 1/2" per foot of slope, about 7/16th" per foot to achieve the 2" drop over the 4-1/2' or run. 2) Keep the drain where it is in the drawing and the slope as depicted, from right-to-left. Add a 2" curb at the shower entry. Not curbless, but a 2" curb. 3) A hybrid of the two previous examples. Add a 2" step up at the shower door entry, then have the floor slope away from the shower entry towards the right wall, with the trench drain on the right wall. You'll have a 2" step up but then the floor will slope down within the shower. One note: Even if you did a true curbless like in example #1, I extend waterproofing out of the shower and on to the bathroom floor for several feet. You need to account for not just the physical size of the potential pool of water, but also the wicking and capillary action that will pull water away from the pool....See Morecurbless shower linear drain questions
Comments (35)Sorry to tag on to the end of this thread, it's already a bit messy to say the least. I have spent countless hours researching linear drains and am at my wits end! Bathroom floor is dropped by 1-5/8" from floorboards (2-7/8" below wood floor in adjacent room) in a 56-1/4" x 90" area ready for this project. I need to place the drain as a barrier by the entry way spanning the entire 90". Cannot go against back wall easily because of joist limitation.Tile will be sloped in from 14" outside of the shower including capilliary break then up to the back wall, drawing NOT to scale! I will have wedge wire grate and two 2" ABS outlets in to a 3" ABS drain, so not overly concerned about flooding the bathroom. I am aware of the 3" drop and wet room requirements. My main dilemma is how to terminate the linear at each side wall. I saw photos in another forum where the wall tile 'tabs' in to the drain channel, drain channel extends under wall tile at each end. In order to do this could the entire floor and drain be finished first with channel extended about 3/4" past the intended plane of the finished wall? Silicone caulk the drain at each end. Then the walls could be floated in and the tab cut on the bottom of the two opposite tiles that would sit in the channel. Floor will be hot mopped (I'm in California), walls lath and mortar, and the floor also floated outside of shower area. I'm on a wooden sub floor obviously. Finally, I have narrowed my options down to site sizable QM Delmar or the DERA-Line. Both have pros and cons, does anyone have any advice as in 'stay away from' or any pointers re these two drains? I realise the DERA is cheaper, 304 S/S as opposed to 316. The DERA is custom made to exact length rather than site sizable as in the QM or I may not even be asking the question about the walls. I'm leaning in the DERA direction because price is getting high and the wife is pushing to avoid linear, which would pain me after getting this close. The Dera is coming in around $1100 vs $1500. I thoroughly appreciate any advice or guidance anyone can give. Btw, i am not doing the job personally, just due diligence to be 100% certain nothing is compromised or overlooked. Thanks very much in advance....See MoreCurbless Shower with no slope? (Two Drains)
Comments (48)Rai- Yes, it's a Luxe drain. I have a different one in another bathroom, too (one that has a stainless steel drain cover rather than the tile insert style). I'm happy with both. I like Luxe because the build quality is high, they have a pretty wide variety of sizes and styles, and the prices are much more reasonable than some other name brands. If you are interested in this brand, check out the prices on build.com for starters....See Morethatsmuchbetter
