How big should our addition be?

20 years ago

We are in the planning stages of adding to our master bedroom/bathroom area. Currently our bedroom is approx. 19.5' x 14', so we don't want to add to it. However, our bathroom is only 8.7' x 4.9' with a single sink vanity, toilet, and 1-person shower. We would like to enlarge this room to include a double-sink vanity, a 2-person shower (if possible) and a jacuzzi-style tub. We would also like to add another closet (our current one is 5.4' x 6.2') and a sitting room large enough to hold a loveseat, tv, and bookshelf/additional storage.

I'm trying to find out average size of bathrooms that include the things that I described and what would be the size of a comfortable sitting area? The house is ranch style (l-shaped) with the new addition creating a u-shape. Also, if we were to add another walk-in closet would it seem strange to have one smaller than the existing one?

We expanded our smallish (10 by 13) master bath to 17 by 13. This allowed us to have a walk-in shower, corner tub, large vanity and a smallish walk-in closet (nine feet long and 5 feet wide). We only have hanging and drawer space on one side (but it's deep, so very functional), and shelving on one of the side walls. It's enough for us, although, bigger is better. I wouldn't sacrifice a more open feeling and a good flow in the bathroom to achieve it though.

I would start by taking adding up all the rough measurements you need for each section.

Shower-25sf
Vanity - 16sf
Water closet - 18sf
Tub - 32sf
Extra closet - 64sf
Sitting area - 25sf

These alone equal 180sf. Then you need maneuvering room. You may want to start around 14x14 (or 13x15, 12x16) and adjust up from there.

I wish my closet was bigger for resale, but it suits us fine. It's roughtly 8x10 but it's an odd shape instead of perfectly rectangle. Since you are adding this as a second closet, I figured yours about 8x8.

Have Fun!

We just added 220sf & that included our closet which is approx 11 1/2ft x 7ft. The vanity is 72", the shower is approx 4ftx5ft, the water closet is a little small, its 53"x32". We have a corner tub which is 60"x60". It isn't finished yet but it looks like it should have enough room. We are using the existing space from the old master bath for our sitting room, it will have a comfy leather chair, mainly just for reading. Hope that helps a little.

Thanks everyone for the info! It should help me in estimating the size of our addition. I'll post again when I have more info.
