You can use a base shoe moulding or you can scribe the bottom of the base moulding to follow the floor.

To scribe, you tack your base just to hold it up, then if your widest gap is 1/2", you can take a narrow scrap of 1/2" thick wood and slide it along the floor.. marking the top edge of the scrap with a pencil. Then cut along the line. You would need to do this to every piece of base in the room... wherever the base is continuous.

normal, unless your flooring and walls are perfectly plumb/level.

run a bead of silicone caulking between the two. no shoe molding in a bathroom.

If this is outside the shower, why are you worried about water getting in there? random drops here and there shouldn't be a problem.

Thanks well i guess I’m worried most about the area outside the shower -inevitably water will get under there when people step out of the shower. It sounds like putting some caulking down would fix the issue.

ed, yes. make sure it's a silicone caulking. you could do a clear, or get the same color white as your molding. lay down painters tape on the molding and on the floor so you get thin, crisp line. you don't want it to come out in front of the molding. Just enough to fill the crack. it will be waterproof, same as if you did it inside the shower or around the tub.

I would only add to what Beth H said by using a paintable caulking product on the baseboards. If you use regular (unpaintable) "kitchen and bath" silicone, and anticipate that you may be repainting the baseboards a few years down the road, you will have issues.

If you caulk it, it is worth while to buy the little gadget they make to create just the right curve on the caulk. As it dries, it may shrink a bit? Ask about that at your place that sells you the caulk. I think there are many styles to choose from, just get the right one for your job. Ours was about 2.5 inches long and white plastic with a radius on the tip to make a clean job. It really does a great job, better than the finger tip.

Thanks. Appreciate all the responses.

Caulk does have some "give," but not much. Even if the caulk is expertly applied and well-painted, cracks will form because the baseboard slightly pulls away from the wall.

By caulking baseboards, you set yourself up for continually going back and re-caulking for as long as you own the house. Re-caulking the tops of the baseboards, while annoying, will not be obvious since this area gets painted over. Caulking the lower section means applying caulk directly to your floor covering, disastrous to the looks of your house.

Think twice before caulking that much of a gap.

Been there, done that.

personally, I wouldn't do anything to it. if it's right next to the shower do a bath mat. I have the exact same set up w/tile/baseboard right next the tub/shower. if there is any excess water drip-age from feet or the shower door opening, then you just use a small towel and wipe it. This usually only happens when I clean the shower (because I'm rinsing off the glass doors). So not to belabor this issue, but just leave as is and wipe the floor after showering. if you think it's that bad where you have water seeping under the baseboard, then run a clear bead of silicone caulk. It doesn't shrink or crack and it's paintable. goluscombe you need to familiarize yourself w/new products.

Ok, I think I'm going to just leave it as is for now. Thanks again!

Do nothing. Be a grown up and step out of the shower after you shake like a dog, and use a mat. Only a flood would get under there. Relax, it is normal, and leave it ALONE.

Other than your feet, it is even possible to pat dry while still WITHIN the shower.: )

Well gee whiz.........: )

I like your floors :)

Ed,,,here's mine. as you can see, the molding under the window has a gap, even though the floor was leveled. no big deal. I've never done anything with it. my shower doesn't even have glass, but I do have a nice bathmat. if any errant drops make it out, I just wipe it down w/a towel. if that's real marble you have, even water droplets will often leave etch marks. so, wipe frequently!

Cool bathroom!

Actually not real marble- it’s porcelain

Just scribe the high spots. Then caulk the leftover gaps. Don't simply caulk without scribing.
