Adding exterior entrance to bathroom

5 years ago

We recently added an inground pool and are now wanting to redo a bathroom to allow entry from outside. The bathroom we are considering for the redo is a pretty much standard size, 60" x 132". It is configured with a door swing to the left going into the room from the hallway. Looking directly from the doorway is the tub with a (yucky) acrylic shower surround. The vanity and toilet are both to the right and all plumbing is on the right. The home is a slab foundation.

We would like to add an exterior door where the current tub/shower is located to encourage the grandkiddos not to pee in the pool! We know that most exterior door requirements are 32" so our dilemma is the width of the new shower for the reconfiguration. We would be using tile for the surround and not a prefab acrylic monstrosity.

Our idea is to move the toilet slightly closer toward the hallway door thus allowing the shower to be rotated 90 degrees. Although we haven't looked, it is likely that the wall to the left of the current tub/shower location is load-bearing and we don't really want to steal space from the existing bedrooms to increase the shower width.

At this time, we are in the exploration phase and wanting to get suggestions as to whether it would even work. We know breaking the concrete will not be inexpensive but adding an outdoor bath is most likely much costlier.

Any ideas to make this work? Thank you.

    Do you have a picture of the space? Also, are you looking to do a tub/shower or just a shower going back?

  • 5 years ago

    Just a shower as a replacement. Yes, I can grab a picture and post when I get home.

    Here is a picture of the current bathroom. We took out a window above the tub/shower recently.

    It looks like you have plenty of room to move the toilet over since you have a freestanding cabinet in that space now. You need a minimum of 30" for the space for the toilet between the sink and the shower.

    You can have a small door to the outside as small as 28" would be ok.

    Your plan looks like it can work just fine........

    Wonderful! I was concerned about about using a smaller door as an exterior but if code allows it in my county, I'll go for it!

    Another thought I had tonight...move the toilet to the space where the tub is currently located and then the shower would be in between the toilet and vanity sink. I would still rotate the shower by 90 degrees because as you mentioned, the space is available where my freestanding piece is located.

    I was exploring wall mounted toilets and thought it might be an option to increase the wall depth on that right hand wall where the tub water lines/vents are located. Because the wall toilets are not as deep as standard floor mounts, I think the overall dimension of that wall would allow.

    My big concern is planning frugally with my budget and avoid breaking into the slab as minimally as possible. By increasing that wall depth, there would be plenty of space for the toilet mechanics and maybe (fingers crossed) the drains would be close in alignment. Then pipe sizes would need to be changed out because of going from tub drain to toilet drain.

    Overall, our ideas for the space and the solution to our needs are less costly than building a small cabana type structure with a potty. We explored that option and it was just too prohibitive.

    IMO we need to see a to scale floor plan showing how it relates to the inside and outside of the home.Do you have access to the plumbing from a basement or is this a slab. Moving toilets is expensive.

    Moving your toilet over one foot plus or minus is not too expensive....Have a licensed general contractor make the changes for you.......that way the work will be warrantied for at least one year. Verify this with your contractor.

    Being on a cement slab should give you pause in relocating plumbing. There is additional costs and it should be discussed up front with your contractor.

    Is this the only tub in the house? If so , I would not get rid of it.

    Can you draw a floor plan with dimensions and what is behind the right wall of the bathroom. If you are going to a smaller shower, you will need extra inches bumped into the next space.


    Hope this helps explain what I'm trying to write!

    Good luck!

    Thank you.

    Debbie, we have three full baths in the house, so losing a tub isn't a problem. Even losing the shower wouldn't be a huge issue, although it would be nice to keep for washing off chlorine after swimming.

    I completely understand your visualization and pushing into the space to the right would work as it is a closet in the adjacent bedroom. Another option I saw was a curved front shower, but not those ugly round corner units. It was tub size shower pan that was slightly narrower on each end. It would work but it didn't really "wow" me.

    I'll put together a quick floor plan with dimensions for everyone to see. I believe the home builder probably had an option for a double sink vanity in the bathroom as there are 3 bedrooms on that side of the house. The original owner chose a single vanity so I have wiggle room along that right hand wall.

    Thank you for the head's up on warranty issues. It wasn't something we had thought about quite yet, but I'll definitely put it on my "must have" list.

    One more thing .... in addition to the indoor shower you might want to add an outdoor shower on the same wall where plumbing is already in that wall..... we have one outside our house because we live near the beach ... it’s the best thing we’ve ever done ... plus we wash the dog there too.....

    Since the homeowner said they already have a few other baths in the house, could this bathroom be reconfigured so that there’s an outdoor shower with drain (for washing off chlorine) and then make the interior space just a powder room with hooks and space for towels and such?

  • 5 years ago

    Lampert Dias & AJCN, your thinking is very much in line with ours. We even thought of changing out the existing shower to a dog wash area!

    The biggest problem we want to solve is providing easy access to a toilet area without trailing throughout the house to reach a potty, hence access to a bathroom directly from the outside. We learned from another home which had a pool, that easy access to a bathroom is a very nice perk. After a few of the littles slid down on floors trying to reach a bathroom, we want to provide an better alternative. Also we entertain quite often and want our home to be accommodating to our adult pool guests.

    And AJCN, I need to come up with a idea for wet swimwear and towels. I want to solve the utilitarian issues firstly with the decor coming next. Honestly, that bathroom hasn't had any thought put into it yet to make it attractive. At this point it's just another room that came with the house! Lol

    Whoa! never thought of that! It's so different that I'll need to contemplate for a moment!

  • 5 years ago

    PS We were going to convert to a shower only so this would be an easy solution!

  • 5 years ago

    May need frosted doors similar to this if it is allowable

    That's exactly what I would do.

    I wonder what they used in the first photo to waterproof the door frame itself. The door could be fiberglass or even steel and the door threshold could be tile. Maybe using quartz trim with caulking around the interior side of the door frame?

    This is definitely worthy of exploration. Thank you for this idea.

    Is it important to you that the bathroom remains accessible from inside the house?

  • 5 years ago

    You said the bathroom is 60“ x 132“ which is 5’ X 11’. Is that right?

  • 5 years ago

    Yes AJCN, as there are three bedrooms on that side of the house, the bathroom needs to remain accessible from the inside hallway. See the floor plan that I posted a few replies upward for all the dimensions of the room along with the callouts for electrical, fixtures, etc.

    Sometimes it pays to keep in touch with old friends so I pulled in a favor! Lol

    It’s been a couple years, did you go through with this idea? I’m considering it in my walkout basement.
