if it's a separate room, I would tile the floor.

a great tile for sure, something that sets the tone of the house and compliments the wood floor.

Based upon the information provided: Tile.

Has construction started? Are you open to layout improvements?

I am a huge fan of slate tile. It has a wonderful "warmth" that you can't get from porcelain and complements the natural wood flooring.

Google Vermont Slate.

I had black, green and purple variants in my last house. They looked great after 28 years, had a great feel under your feet and were not the same old, same old...

Normally the guest/formal entry of a house would just be a foyer. In the USA it is unusual to have a mudroom or laundry in that main/formal entry.

Is this your formal/main entry or everyday/family entry? Your only entry?

What is your climate?

Thank you all for the responses!

@Mark Bischak, Architect - construction hasn't started but we are in the process of ordering a LSF structure. Curious what improvements you may recommend!

@just_janni I am also a fan of slate, it was on the top of my list :)

@chispa - we only have one entry to the house - so it's a formal and everyday entry. We have young kids and a dog. We're in Central Portugal, so have a warm, midlly humid climate in summer and very wet winters.

Some of it depends on your practices. Are you going to have a porch with a good mat and get the snow/mud off your boots before entering? Or will you have kids who tramp muddy snow in the house? Do you live in a warm climate and stick to relatively clean sidewalks?

@just_janni - I am a slate fan also!

@dcmohan - I am having dark charcoal slate from Brazil installed (4" x12" size in a herringbone pattern) in my mudroom/laundry room combination. I also have it installed in a bathroom upstairs. It's very durable and feels great.

Mine is honed + gauged = easier for tile installer because pieces are the same size. There are some pieces that don't have a smooth (honed) surface - but there are quite a few that do.

Slate from Brazil is very durable (Vermont slate is very durable also - I am not sure of all of the available colors). You need to make sure that you don't purchase inexpensive slate tile from China + some other countries.

Slate from Vermont and Brazil doesn't flake (have cleavage/fractures) = the top layer peels off over time. Also, it isn't slippery (I had someone here on Houzz tell me how dangerous it was to use slate tile in a bathroom - but I had already researched slate from Brazil and knew that it wouldn't be slippery).

A powder room that is 1.524m by 1.524m is sufficient. There is more space in the powder room than is required and that extra space could be better used elsewhere. I never put a barn door on any type og bathroom because it offers limited privacy in many ways.

Thanks Mark! Local code dictates that the bathroom needs to be a little larger for wheelchair accessibility, and yes we’re already on revising the type of door - thank you!

You have so many great tile options in Portugal, and so I would definitely want tile. Wood is not practical for wet areas - or even damp areas - and I would not even put wood on a kitchen floor.

I'm in Palm Springs, and all my floors are porcelain tile, but I have area rugs in the living areas, but not the dining area.

Properly sealed wood is absolutely great for kitchen floors. I've had tile, laminate, and vinyl in kitchens, and my favorite and easiest to care for is wood.

For a mud room, however, I think tile is appropriate. You just need to figure out the best spot to transition from the tile to the wood.

"so have a warm, midlly humid climate in summer and very wet winters."

Consider engineered floors (I don't mean LVT). Engineered hardwood is perfect for your climate. Install factory prefinished, it's tougher, and buy a small rug for the entry that you can wash.

I'm a white hardwood fan but draw the line at a laundry room. Tile it is. I would make the laundry / mud room subdue in color and texture. Draw the focus to elsewhere in the house to that your eye is lead to something other than laundry.

I think tile is best and in Portugal the tiles are fabulous if this space is on display do one of those fabulous tiles in colors that work with the rest of the home.

Beautiful, chispa! The transition was so very well done.
