Sheet vinyl will most likely be more cost efficient. If you were to damage the sheet vinyl you would need to replace the entire area or cut out and patch (which can turn into a disaster if not complete correctly). With LVT you can pull the plank, clean glue off subfloor, add new glue and replace. Very simple. Are you looking at a glue down vinyl plank or a floating vinyl plank?

@V M sorry, just seeing your post above. We are just now finally breaking ground on our home so I don't have pics of the flooring to show you from my house. I will come back and post when I do but that will be some months from now. But we are paying, I think, 15K for our Multi-Length Rigid Core SPC floors in color Sandhill. Our house will be 2975 sf and this floor covering will be throughout the home, except in 3 of the full baths and the utility room. I'm not exactly sure how many square feet that leaves but hopefully you can do some rough math. Everything goes through my builder so I don't have an exact price per square foot to provide you. I also am not sure if this includes labor to install.

Installing hardwood in Florida takes extra effort. The first part of that effort is having EXCELLENT humidity control in the home. In hot, humid climates that means the A/C might not be enough. It might require an additional whole-home dehumidifier. It can also rule out an 'open window' type of home. Again, it depends on the location and the humidity levels. Hardwoods must be kept in a 'happy humidity' range between 45% - 60%. At all times. Every minute of every day. For ever and ever. And ever and ever. That means you will spend more on your HVAC system to have that type of 'push button' control (whole home humidifier/dehumidifier). And then the type of build also dictates the best practice for installation of hardwoods. A concrete slab takes extra effort to glue down wood. A high-end adhesives must be used and those add $2-$3/sf...just for the glue. The hardwood and labour are on top of that. In Florida, the most appropriate floors are stone, tile, terrazzo or concrete. All of which are hard and cold. Of course a cool floor in a hot climate is a BENEFIT...not a drawback. Part of the cold flooring is it helps keep the house feeling cool. Vinyl is then the next option. The difference between the 'wood look' or the stone/tile look is simply aesthetics. If you LIKE the look of wood, then go for it. If you LIKE the look of stone/tile, then go for it. With vinyl you will require very good UV block on your windows. Ask your builder what level you have on your windows right now. You will want to find something with UV block ABOVE 50%. I prefer to see 70% - 75%. That keeps the vinyl and the house cool. But it also makes growing indoor plants a difficulty. Plants struggle with UV blocking windows at 70% or higher.

Sheet vinyl is the only 'vinyl' product that is 100% water proof. Even if it has a seam, the installer will 'weld' the seam (either chemically or thermally). That means a sheet product is EXCELLENT for 'leaky animals' (including humans in a splash zone). I'm not fond of sheet vinyl in a dining room (formal especially) but 'eat in kitchens' have often been covered in sheet vinyl. It all depends on the space. Vinyl planks have seams. Thousands of seams. Each click edge (4 sides of every plank) has a limitation. They can be water resistant (a large spill = gallon of milk = stand for 24 hours without issues) but are never 100% water proof. Ever. The gallon of milk may not seep through to the subfloor BUT the milk will settle in between the planks = no amount of cleaning will get it out. That's when odours occur. The milk, being an example, will sour and then you have a large patch of flooring that smells like sour milk (because you couldn't get every stick of milk out from between every single plank). The same thing happens with body fluids from pets. The planks can prevent the urine from reaching the SUBFLOOR but it won't stop it from pooling in between the planks (in the seams). I have a soft spot in my heart for sheet vinyl (for some weird reason). I think it is a product that has EXCELLENT properties for certain situations. Not everyone 'needs' those properties. That's why vinyl planks were invented. It makes people feel like they've done something 'good' for their home. Which can be very true. Your personal situation will dictate what you use. If you need water proof (ie. snow/rain has to be stopped at the doorways) then sheet is your go-to product. If you have an area that gets some splashes from the sink but nothing more than that, the vinyl planks do very well. Dog drinking bowls are known to cause 'bigger than we thought' water issues. And dogs will age. Sad but true. Photos of your space will help us understand what's going on.
