IMO a guest bathroom needs more counter and no dressing table. I would not have a lower counter for makeup if you insist then supply an adjustable stool. As for placement of sconces that is best decided with a piece of graph paper and the measurements of the sconces and mirrors then draw to scale until it looks right.

Good recommendations. Thank you. We didn't plumb for double sinks so I was trying to make use of the 70"s of counter top. Plus when elderly Mother visits dressing table may come in handy. Would you have put in two sinks?

No IMO guests need more counter than what you would need if you lived there and IMO 70” is not big enough for 2 sinks

thank you!

Agree. An overnight guest would need a place to set a toiletry bag /wouldn't "move into" the drawers.

Have you looked at vanities yet? I don't think 40" is a standard size -- probably 42" or 60".

I'd consider a linen closet in place of the dressing table.

Reasonable. I'd go with a stool (rather than a chair) so it can be "tucked under" and not be in the way when not in use.

No.

I really appreciate all the ideas., and hadn't thought of the idea of needing counter top to place articles because -yes they don't use drawers and need extra space. One more question...wouldn't a "dressing" table work the same as vanity top? The only difference is the 30" top in dropped down a couple inches. I can keep it all one level but there will be a seem because that's the size of material available.

Not a response to the vanity question, but a response to your mother’s visits. If you have not already tiled the shower, now is the time to put blocking in the shower walls for grab bars. When we built our house, we put blocking in the walls in each tub or shower in anticipation of visits from my parents. We also included blocking in our shower. There are many good looking grab bars that don’t resemble the hospital grab bars which look horrid.

Great idea! Thank you for thing of us.

Hey, we have lots of sconces that are narrow enough to fit between your mirrors and all of them are available in any of our 200 color options to make sure they look great in your space!
