Diffrent question: How much time do you/significant other actually spend in the shower vs at the vanity? What sort of things do you need on your vanity?

One more- how much money and or time do you have to clean the shower?

Answer those questions honestly, and you come to an answer that is perfect for you. But be honest.

And please- get rid of wood in a wet area.

There's a walk through dressing room off of the bathroom with a sitting area for hair/makeup so we don't need much storage/counter space for the vanity. At the same time we don't hang out much in the shower either. Just in term of look and design which do you think would look better? Would a double sink vanity be better or a big shower in terms of resale?

And yes, we are definitely getting rid of the wood...that photo is how it looks now and we'll be doing a total gut.

I think resale, on huge showers, is an open question. Not sure your age, but there was a time in the late 80's/early 90s when the RAGE was huge bathtubs, in masters. They were sexy- hot tubs in the bathrooms! Looked cool, too. And then a whole lot of people spent some decent $$ on tankless water heaters, just for their tubs. And the rest of us ripped them out, in favor of bathrooms that didn't have all that maintenance. I say this as a person who has a "soaker" in the house- my husband. He has a freestanding tub, all his own. But it isn't "Scarface", and he can actually use it with no extra "power". Just make sure your shower is the same. We're all humans.

Whatever you do, make sure you have heat source dedicated to the shower, if it is to be that big. Separate from anything like laundry area or dishwasher or even a toilet flush, in the bathroom. Otherwise, you will have "water confusion". And truly- make sure of two more things:

1. Ventilation- as my architect and contractor called them, fart fans. Humidity, with those big showers, is a real problem. It gets steamy? Great. Then you get to deal with all the mold an mildew that naturally grows.

2. Understand the cleaning necessary to keep it fresh. That includes all the fun hoses/rain showers etc. If your huge shower starts to feel like/smell like a Russian bathhouse in NYC, you may not love it.

It all matters.

In that size bathroom, two sinks are mandatory. After that, a roomy but not-too-big shower with a smaller soaking tub is preferable to a smallish shower and a big tub. If you don’t have room to make it comfortable and luxurious, skip the tub altogether.

The best "bang for your buck" is a shower width (facing the shower head) of 42 inches, the length isn't nearly as crucial. Another option is a small, very deep tub with jets designed for your needs, Diamond Spas is one manufacturer. I don't consider a 60 inch vanity sufficient for a MB regardless of having a separate area for make-up. Just MO.

I think 48 x36 is the perfect shower size, it’s plenty roomy, it doesn’t feel drafty like larger showers sometimes do.

Had a similar decision to make recently. I had 2 final layout options: the first had a 90" vanity and 4x6 shower. The second had two 48" vanities and a 4 x 5 shower. Based on input from two designers, we chose 48 x 60 shower with rain head and regular head with two 48" vanities. The designers input: The long vanity was heavy looking and overwhelmed the room (similar size to yours); the double vanities are on trend now; this layout has the toilet our of view. Here's out layout. Maybe it will help you decide.

Con of a big shower..... not small enough to stay warm. i love hot showers and the only thing worse than getting out of a hot shower into a cold room is standing under hot water in a cold shower because it is too big to stay warm!

So what size would you say is small enough to stay warm?

You could probably go as big as you felt comfortable with as long as it is completely enclosed. The more open it is, the less warm. I do a lot of stone for bathrooms and i have noticed complaints once people branch larger than a 6x6 shower. especially without being enclosed.

if you put a combo heater/vent in the ceiling over the shower you wont have an issue. our shower is 5' x 8', open, and we're warm as toast in winter. when we've toweled off we switch it from 'heat' to 'vent'

I just read your comment where you say you use a big jetted tub for back pain relief. Since that’s the case (and boy can I relate) forget what I said earlier, please. Find the best tub for you and work in everything else around that. :)

I like a big vanity because I have a make up area built into mine.

A big shower is hard to keep warm and I end up cold. Not conducive to shaving legs!!!

Thanks everyone for your feedback! I think I'm going to go with this revised layout. Tub can be big (space for up to 90"x42"x27"). 6' vanity, 4' shower and toilet isn't awkwardly in front of the vanity.

I think that layout works great!!!

Ninigret, could you share more about the combo heater/vent you use for your open shower? Or perhaps a photo of your shower? I am trying to determine if we could do something like this in order to have an open shower.

Just want to mention one thing to anyone thinking of having a very large (long) tub. I wanted a really large tub.....love to soak. My thinking was the bigger the better. Ours is 75” in length. Nice and long. The problem is that it‘s so large that my legs are not long enough to brace myself against the far wall of the tub, so when soaking my body just keeps slipping down into the water. It never dawned on me that it’s necessary to be able to touch the end of the tub with your feet in order to keep from slipping down. Instead of a nice relaxing soak, it was a constant strain to support myself.....not at all what i had envisioned. When trying out tubs in a showroom this problem does not become apparent because there is no water in the tub and your fully clothed (hopefully) so everything seems perfectly fine....there is no slipping. Once there is water in the tub though, the dynamics change completely. The only way I was able to solve the slippage problem was to use a heavy duty plastic tub mat with suction cups on the bottom...that helps keep my body from sliding down. But still, it would be much more comfortable to be able to brace my feet against the tub wall.

Thats a huge tub! Much better layout... I would either do a beautiful free standing tub with an amazing feature wall of tile behind it or do a 6ft deck mounted tub...
