Make sure you look for a water resistant laminate because most laminates don’t like water. We were looking at AtroGuard laminate by Lamett, but have since decided to install SPC (stone polymer composite) rigid plank SuperCore flooring from WeShipFloors.com. It’s not bothered by moisture and humidity, and living in Mississippi that’s a real plus. With the laminate we would have to run dehumidifiers 24/7 to maintain the 40-60% humidity to keep it happy during the summer and humidifiers in winter to maintain the humidity during cold weather when the heat has to be on. Most of the water resistant laminates are surface water protected for up to 72 hours, but if water gets under it the floor can be ruined. The Flooret Modin SPC plank has some colors you might like and so does SuperCore. It’s definitely worth reading up on the newcomer SPC since it can take temps much higher than LVP and WPC (wood polymer composite) vinyl plank flooring and is much more stable in sunlight. I also suggest you read a lot about laminate since you stated you are looking for flooring that will be durable with water. IMHO, the SPC flooring will fit your needs better. There are some companies that have a tile look SPC if that interest you. It may take some research to find them, but they’re out there. Good luck in your flooring search. I really suggest you do some reading on both types of flooring and then decide what you think will work best on a concrete slab in Florida that needs to stand up well to water with humidity, kids and a dog in the picture.

Kristine Kelly, At first I was using premixed Murphys Oil Soap that comes in spray bottle. Supposed to not leave any residue. But after a lot of research am now using just plain water. Works well. Shaw makes a spray that you can find online too. Haven’t tried it yet.

I understand why it must seem confusing. Ideally I would use the same flooring however my stairs have bullnosing which I want to maintain. Mohawk don't have available stairnosing that will allow for the bullnose to show and from pictures/videos I've seen it doesn't look great: With LVP there is stairnosing which can just slot into the existing bullnose:

No matter what you choose, just be aware that when you add a layer of flooring on top of existing flooring in your kitchen it is possible to trap your dishwasher and refrigerator such that you won't be able to pull it out to service or replace it. It's more likely to happen with the dishwasher since it is trapped by the counter. Sometimes refrigerators have some wiggle room at the top. This has happened to me and one of my friends. The people laying the floor don't care because it's not their problem and their livelyhood depends on them not telling people about it. You will get more comments on your question if you post pictures of the colors that are available for you to choose from. It's even better if you have brought samples home and can show them against your cabinets. If you're doing your whole first floor with it you need to also be thinking about how it's going to look with your furniture in the affected rooms. The one thing I will say is that gray floors are a dead trend on the coasts already. If they're still popular where you are you can expect it to be a trend that won't last much longer.
