Curbless Shower Installation Wood Subfloor | Part 1

Ойын-сауық

Installing a curbless shower over a wood substrate is a lot easier now than in years past. Topical waterproofing and foam pans make the installation a lot faster and there’s practically no notching of the floor joists involved. In fact there are many sizes of foam pans available that require zero notching if you use a 1/4” underlayment outside the shower. This particular job did require notching the joists down about 3/8” which isn’t enough to worry about added deflection.
The first thing you’ll want to do is cut out the subfloor where your barrier free shower is to be installed. Once that is out of the way the next step is to install 2x4 along each side of the floor joists. You will need to add up the heights of your shower pan and subfloor thickness then deduct the thickness of the underlayment outside the shower to know how far down to install the 2x4. It’s better to error slightly deep than too high on the pan.
Once your 2x4 has been installed, cut strips of plywood to go between each run of floor joists. The plywood does have to be fully supported, so you may have to add additional floor joists or blocking as necessary. Our job was very accessible, so we added two more floor joists on each side of the pan. The new joists do have to be installed so that each end is resting on a beam or support.
Our next video will show you how to install the underlayment outside the shower and get the shower pan ready to install. Be sure to watch for Part 2 coming up.

    How do you build curbless showers? Does the new materials make it more likely that you would want one in your home?

    Well after watching yours and Schluter videos, I'm doing it just like that. Quick question. What happens if the shower pan drain hole falls right on top of a joist? Would I be forced to cut my schluter pan so that the ends are no longer equal distance from the center of the drain? I imagine that changing by 2"-3" wouldn't be a problem?

    @@cwb124 you’d want to move the pan over one way or another. If a level perimeter is important to you I’d have a custom shower pan made. Built With Foam is a great place to order from and they have fast turnaround. They will make a custom pan with the drain located where you need it. The perimeter would then be the same height all around.

    My new building has the I beam joists made of OSB. I doubt I should take any of that material off like you did here with just over 3/8"??? That would compromise the strength of the joist??

    +The Invitation You would be correct. I Beam joists cannot be cut down at all. If you remove the 3/4” plywood subfloor exposing the top of the I Joist you can sister lumber to the sides of the joist. Once you have the sides built out flat you can then sister lumber 3/4” down from the top of the joist and cut strips of plywood to fit between them. This lowers your floor 3/4”. Most foam pans are 1” at the perimeter and if you then lay 1/4” thick material in the rest of the bathroom you have a curbless shower.

Worth checking out if you have a few days.

    I find it hard to do a curbless with a linear drain. Some guys put the drain at the door and slope the floor up from there. The water then runs toward the door and some will escape. Putting the drain against the wall requires a deeper floor recess. It can be done, just a bit more tricky is all.

    Ditra is 1/8” thick. There’s a solid hardwood floor at the transition of this bathroom. Cutting less than 1/4” off the top of the floor joists doesn’t change their deflection and load, it does allow us to use regular Ditra and have a flush transition at the door.

The issue I see is the straightness of the cut with the hackzall.. so if the pan is ¼ above.. can't you slap something ¼ plywood down?, So then how would you transition to for eg; Pergo+LVP in the rest of the bathroom floor? And then, a transition strip at the br door???

    If you're "sistering" a joist to regain strength, you need to go from beam to beam and put a lot more fasteners in it. The sistering you did here accomplished very little, if any, added support. Ideally, you would have sistered them with another 2x6 that is cut down to the same dimension and then shoot 2 rows of nails staggered at 12"-16". You'll probably get away with it in this case, but keep this in mind in the future.

    We aren’t cutting into the joists enough to change their load ability. The 2x4 is only to hold up the plywood. The building inspectors in our area aren’t concerned with notches less than 1/2” deep. We cut this down about 3/8 which is roughly 1/8” more than we need.

    @@friendlyneighborhoodtileguy Understood, which is why I said you'll probably get away with it. I was just pointing out that the sistering was not effective in adding strength to the joists as you stated in the video. More for the benefit of people watching this video and thinking this is the proper way to sister a joist. I'm a home inspector and I see improperly sistered joists all the time. It would have been better to say that the 2x4s are there only to hold the plywood rather than to say that they make the joists stronger than they were before. Accuracy is important.

Plumbers can set the drain and I could set the pan around it and be compliant if a licensed plumber is necessary. As long as everything is set in mortar correctly there is no issue with it being done this way. Thanks for commenting, I appreciate it.

There is a vanity, laundry and stool above the shower connection and showers don’t have many solids go down the drain. I’m confident the odds of a clogged drain pipe are very low. Do you disagree?

    The size of the drain is fine and blocking is not necessarily a concern. You are not allowed to have a TY fitting on its back and after the p trap you installed a 90 degree elbow pointing down. By doing this the shower is no longer vented. Next time install a wye fitting on the side and have the horizontal section after the p trap go into the wye. You are allowed 135 degrees of charge before your vent. This design is also assuming the larger drain your connecting to is a “ wet vent”
