Personally I don't think that 3 full baths is a huge selling feature, especially at the expense of none of them having a tub. If the space would work as 1 full with a tub and a half for guests that would be ideal. Otherwise, I'd stick with one big bath.

We have a powder room and a full bath in our house.

My uncle is an interior decorator....we have the option to add a 3/4 bath (shower only) to our master bedroom, OR to expand the existing full bath into one large bathroom. He suggested that we expand/remodel into a larger full bath, leaving us with the same 1 1/2 baths. This is from an interior decorators standpoint, and also someone who doesn't have children.

I'm more practical. It doesn't make sense to me to spend the money to expand the existing full bath into a larger bath from a standpoint of resale value, when I could sell this as 1 full bath, 3/4 bath, and 1/2 bath. Would I love to have that huge full bath? You bet. Does it fit into our current home? Nope.

We live in an English Tudor style home, the rooms are typically small scale, with little closet space. Lots of character, spanish plaster, hardwood floors, etc., but that's the trade off.

Our full bath measures (tile to tile) 4'8" x 7' 4". By no stretch of the imagination is this a large bath, but it is a full bath nonetheless. You can't use the commode and open/close the door (not sure that you'd want to anyway), because your legs are there. Next to the toilet is the sink, and directly next to that is the tub, and the linen closet is in the hallway. Our powder room measures less than 5' x 5'. Again, small, the door would swing onto your legs if you are on the commode, and the sink with a counter/cabinet that runs from wall to wall, is right next to that.

So, based on your overall measurements and available space to work with, if you really want a full bath and either a powder room or 3/4 bath, I think it's doable. Small, but doable.

I personally would look at it from a standpoint of who your market will be when you sell. We live in a neighborhood comprised of families with children - that's who our market will be when we sell, so I'd rather add a 3/4 bath to our home than to make the one full bath that we have a bigger one, based on practicality alone. And, children or not, I personally wouldn't purchase a home without a bathtub. But that's just me, I'm a girly-girl and I lOVE taking bubble baths.

Good luck with your remodel, whatever you do. Don't forget to take before and after pics!

Duh, you'll have to excuse me, I had a momentary brain freeze. I was calculating square footage, so I don't think you'll have the room for what I was suggesting. LOL. It's been a long day, and I'm only halfway there... ugh.

You didn't say what the real purpose is, or maybe whether you see a deficiency in your current set up.

In my area there is no "norm" besides in new construction. In new construction the "standard" is 2.5 baths. 1 master, 1 main, 1 half downstairs.

I personally don't see that much of a benefit in having 3 3/4 baths, unless there is a need for it, ie: other adult moving in deserving of a private bath.

My vote is to keep the 3/4 in the master and the other large bath. It will be cheaper, and I doubt that from a resale perspective you'll have bump having 3 3/4 and you might be hurt not having a tub in the house.

The builder who constructed our neighborhood of houses back in 1956 allowed buyers to choose between having a larger (8x10) bath on the bedroom level or 2 small baths in that 8x10 space. Our house has the larger bath, and our neighbor has the 2 tiny baths, one with a shower and the other (slightly the larger of the 2) with a tub. I do so wish we had the 2 tiny baths! We have a second bath with shower on the family room/guest room level, so we are not short of bathrooms, but it would be much more convenient for us to have 2 of them upstairs.

Although I can admire large, spa-like baths in magazine photos, I have no desire to live with one. Practicality is key for us, meaning we prefer baths that are easy to keep clean, warm up quickly when the heat comes on in the morning, and are easy for people with bad balance/stiff joints to maneuver in (the smaller the bath, the easier it is to catch yourself before you fall).

We have no use at all for a tub, but I do think not having one is bad for resale. Unless you have an unusual number of doorways to accommodate or other odd configurations, a 12x8 space would seem adequate to hold one full (tub w/ shower) and one 3/4 (walk-in shower) bath.

Here are a bunch of bathroom layouts. You didn't say whether you can split the bathroom into two 6 x 12 or some other way. If it's 6 x 12, there are at least 2 plans that you can adapt to your needs.

My hubby and I had that exact same situation, and we opted to do the 2 small baths. Our 2 baths are 5' x 8' and are back to back. They both have a tub/shower combo 24" sink, and toilet. Small but functional, and I wouldn't have it any other way. We have 2 small kids and I can't count the number of times that both bathrooms are in use at the same time. I think if we had one large, beautiful bath, we'd enjoy the looks of it, but we would also have alot of banging on doors and fighting. Easy decision.
