Good job. I just watched about 8 videos on shower installs and plumbing for showers and yours is the first one that is decent and educational. The rest of the ones I seen we're giving more bad advice than good. But at least they reminded me of things not to do.

[@MrPostFrame]

[@davidfrankhauser1666]

We used to run mortar to support the center in order to prevent cracking. Love this build!

[@BZ1340]

We still do run mud beds under all our Acrylic Tubs and shower pans. OR we use spray foam. We have drains cracking around the drain flanges on the tubs especially. The weight of people standing in the drain areas was causing stress on those areas. Yet the tubs and showers had plywood fibreglassed in legs and platforms.

[@jwpepper6718]

I was going to say we use structolite under our tubs/shower bases for added support.

[@mkzenthusiasts]

Yes, he could still pack mortar under it or better yet spray foam could get sprayed once he can fill the tub full of water closed cell foam would add structure. I have also see drywall mud used as well

[@rkalle66]

@@mkzenthusiasts Spray foam is soft. In my opinion not so good to add to the structure. Mortar or lightweight (foamed) concrete will do better. Consider acustic butyle mats on the tub walls, too. It will improve comfort.

I’m a kitchen and bath remodeling contractor in Southern New Jersey I always put structalite which is the base coat for plaster walls it’s great for sound deadening tub bottoms and a great leveling base you don’t get that hollow sound when your shower hits the especially on upper level bathrooms you don’t hear it in say your den area watching tv

I suggest that you install an access trap door tall enough to cover the shower/tub controls (just in case the have to replace it) and going down, to gain access the the swival "p" trap drain below the floor.

To make it more comfortable, less drafty and be able to replace the one piece tub in my bathroom and take the time to make sure its perfect and get any proper new parts i need.

[@thelostarchivesserialvault5353]

I hope you remember to install some support for the center of the tub. I use spray foam before. If you don't support that section you run the risk of it cracking and creating a leak. That is fibre. Set the tub then come back with some spray foam from the side. Just use the non-expanding filler.

[@MrPostFrame]

Thanks for the tip!

[@laptopstylelife7050]

Amazing tips once again. Rubber connection, access door, etc. I would use some sort of spray foam or something of the like under/around to base of the tub. It will make it way more solid over the years.

[@BasiCommonSense]

may i suggest the shower tub must be set in structo-lite plaster or mortar. Ive done plumbing for a good portion of my life and setting fiberglass tubs is and was an everyday thing. if something heavy falls in tub person, kids jumping up and down or what have you it will break the tub. the base must be set in mortar or structo-lite

[@johnpyle8027]

I built an earth contact home so I am no stranger to concrete floors and plumbing and if I did it again I would do some things different. I am alone now son not all the tubs and bathrooms period get used. I had company once and my shower, much like the one you installed. The drain lost its seal where it is screwed to the bottom of the tub. I turned the water off and messed with it later. NOONE could sell me a drain that I could install from the top at the time so it remained unused for some time. Then one day I saw on here a new top install drain. It slides over the rough plumbing and rolls on a greased grommet. The ring is self tightening by 5 fingers you set and when you start turning the screws the grab the bottom/floor of the unit. I don't think anyone used any support under the units. When I built my other houses I dumped a wheelbarrow of concrete in and set the unit in that and never had problems. Anyway they have all that stuff accessible from the top now.

Your video saved me so much frustration and probably a broken shower. I bought the exact same model and nowhere in the instructions does it say to use 2x4s under the feet. I was about to screw it in place and then shove shims under it which probably would’ve softened and then shattered the flange later on.

[@MrPostFrame]

Glad we could help! Thanks for watching!

[@briancorbett793]

nice job sir. I have seen these fail over a long time (25 years) due to no support under the tub, like mortar or foam or similar. after several fatigue cycles of a 200lb person plus water, possibly like 400 lbs of weight on the bottom. plus if you do it will take any of the "squishy" feeling you may have when you step in it. It may feel stiff now but over time may weaken.

[@joopterwijn]

It is a bit late now, but before installing the shower tube, spray foam the bottom and back of the tub a day in advance installing. Great sound insulation and your tube water keep the heat longer.

[@nakantor]

YES!!! I spray foamed under the tub in the basement bathroom I finished and it's great. Very solid and slows the water from cooling off. I actually foamed it in place.

[@ShainAndrews]

@@nakantor I've done it in place as well. I did it more to make it feel more stable, and eliminate creaking noises while in use. Bugs me when I'm in a well built house and the shower feels like I'm in an RV. Extra insulation was a side benefit.

[@pamf1890]

Just watching your videos now. Did you brace the bathtub with anything else? I have heard of people putting more of a structure underneath than just the feet that are built into the tub. Do you think that would ever be necessary?

[@Flyboy-ww7og]

Ive seen where lots of people will set the tub in mortar for support over the life of the tub. Do you have plans to insulate behind the tub? I like the spray foam idea for added tub insulation to keep the water warmer longer. On your wall sill plates, besides tap-cons for anchors, I have seen adhesive used between the floor and plate. Any thoughts on adding a beed of calk under the plate? Even to keep water contained within a room?

[@throngcleaver]

I wish I had done that when I replaced my tub in '07. Every time I step into it, it creaks and moans, and I keep thinking it's going to crack at some point.

[@BarryLawrensen]

How about using spray foam, sprayed in after the tub is installed, to support the center portion? I have a tub/shower I installed 25 years ago, and the center sags now when I take a shower. I might try to put some spray foam underneath it (I have access from below).

[@shutterbugg5217]

[@wrfarms9741]

Is the box in the concrete slab that you brought up to shower/tub drain protected by a vapor barrier of some sort? I askings because I am installing a 42" x 42" corner shower in a basement slab with 2 inch drain. Trying to figure to the best way to pour the slab but be able to plumb the corner shower drain later. I am VERY hesitant to pour the basement slab concrete encapsulating the shower drain p trap. Thanks! Nice work by the way!

[@RandomYTStuff]

1) The drain-tubing, should it not be linked "female" to "male"? so that there is no "lip" inside of the drain-tube that might stop the free-flow of water and perhaps compromise the seal over the years. I think you put a straight tube (male to male) linking the drain from the bottom of the tub to the vertical tube; might not be "best practice" and cause issues along the way. 2) I would try to put some planks/boards under the tub so that it won't be supported only on those small feet at the edges; just prevent/limit the formation of a "curve" in the tub over the years. It make sense to try to distribute the weight of the person standing inside the tub across the whole bottom.

[@HodgePodgeGarage]

right on. I think the angled rubber overflow seal might be upside down though...? If you put the thicker on the bottom wouldn't that make the overflow drain pipe 90 degrees to the ground rather than at more of an angle following the vertical slope of the tub?

[@MrPostFrame]

That’s how one would think it should be but that piece has an angle to it that requires the thicker part of the seal to be at the top which then makes your pipe straight up and down.

[@g_force3857]

It’s hard to see in the video but if I were to set those feet directly on the floor it would not be level. The feet are intended to be set in mortar but I like setting them on 2x4s if possible. I have had good luck doing it this way and have not had any problems with the tub being solid.

Hey

[@travis1555]

Just a thought, at that penetration in the slab for plumbing or any penetration, possibly all exterior walls. Apply some Bora-Care or similar product to the lower 2 feet or so of the studs to stop any future termite invasion. I dont know how bad they are in your part of the world but I could see them coming up under the tub and getting into the framing. Here in the south they spray the sub soil under the slab before the concrete pour. Also maybe a dusting of boric acid powder on the slab under the tub around the opening. Under island in the kitchen, walls, where plumbing comes in before you close it up for ants, roaches etc. As long as it stays dry should work forever. Preventative pest control
