If you are keeping this tub you can't do to much to make the shower bigger.

You could relocate the glass shower surround to the far side of the pony wall which would provide a ledge for bottles and make it feel a little larger.

You can adjust the depth of the shower, adding about 6".

^Yes, it's the same in my area roarah. OP, don't keep the tub for resale if you have one elsewhere.

The only time a tub is beneficial for resale in a master is if it is a freestanding clawfoot style. This space would work a lot better with a large walk-in shower and larger vanity.

Also, not sure where the toilet is but maybe closet it off.

If you have another bathroom in the house and this is the master, rip out the tub and install a wall to wall shower with floating glass door....that is what people expect to see for resale value.

If this is the only bath in the house then install a tub/shower combination unit.

Both look good; shower alone, as shown above, or tub/shower combination, shown below.

A previous house had almost exactly the same layout. Since there was another bathtub in the house, I removed the tub to run the entire width of that wall. No regrets. When we decided to ove, we sold the house in a few weeks.

If you are planning on staying in the house for a while, then do what makes you happy instead of remodeling for retail value. After having lived in the house at least 6 months to a year, ask yourself if you really use the tub
- and if the tub is worth it or if you really would prefer a bigger shower.

Combining the tub and shower would get the most function in this limited space.

If there's another tub in house, remove tub.

Replace with a big walk in shower with seating.

What is your budget?

option 1. $ Move shower head up or install a ceiling shower head. Also move the shower door as much you can out since the wall may allow. Look for larger door with a pivot allowing more width to enter the shower.

2. $$ Remover everything and do a large shower with 2 shower heads and valves.

3. $$$ Hire a designer/architect. They can bring unique solutions.

There have been many answers but the poster is no where to be found to answer questions so we can just keep throwing out ideas for no reason.There is not enough info to help.

Sorry all i’m an Army Officer and been out.

I think ripping the shower out is probably over my budget. I do want to increase resale value but I feel like a better value would be just fixing the backsplash, moving the glass out, and increasing depth of shower 6 inches to be parallel with the wall.

I am open to doing the wall to wall shower, but feel like that’s not worth the $ I’d throw into it

How long are you planning to be in this house? If for any length of time, get rid of the tub and enjoy your new bathroom. If you aren't planning to be there for long, don't bother. But do not let the thought of resale hold you back on removing the tub. If there is another tub in the house you don't need one in the master these days.

Yeah there are two tubs upstairs. It’s a 3 1/2 bath and all 3 have tubs (smaller ones though)

No idea how long I’ll be here honestly. Want to avoid the house becoming a money pit, as the backyard is the big selling point, but also want to do what’s best value, not necessarily cheapest

This is the discussion I am currently having with my husband. This is our supposed "last" home so we should make changes that we enjoy, without an eye to resale. If I had your bathroom, I'd make the shower larger in a heartbeat. Our bathroom would require an architect and an extensive renovation to get rid of the "coffin" shower that we have. But only you can know if this is a renovation that would be worth it to you.

With all do respect, if you're having a problem with it future buyers may, too. If it's the main bathroom, it's a good place to put $ into it when possible.

A good main bathroom & nice kitchen helps sell homes.

I think it's good to do a nice remodel about 5 years before resale, so at least the remodel can be enjoyed & help sell home later.

I'm a real estate agent & can say a lot of people are ripping out the 80s jacuzzi. Installing a sit in shower with tile.

You could save $ doing the tear out yourself.

Careful about the combining into a larger shower idea. We had a similar layout and ran into a $1,600 extra when the manifold that supplied the whole bathroom was located between the shower and tub! Now, this applies to first floor bathrooms on slabs, a second floor bathroom would be easier to adjust the plumbing on.

To be honest, that's a tiny tub anyway...so tearing it out and extending the shower, with a seat by the window, and keeping the existing shower plumbing but using the tub drain could work pretty well.
