Answered

I want my bathroom flooring with MDF wood. Some of my friends suggested me this. Actually I have less idea on this. Even I don't know the basics difference between HDF and MDF. Can anyone tell me the total budget of doing a MDF flooring for 30-40 sq ft area?

I read some websites and blogs

More Links and videos are welcomed for a better outlook

Thanks in advance

    Hi Sussane. MDF is a fiberboard that is often used as a flooring material though it has been falling out of favor because it really can't get wet. MDF stands for Medium Density Fiberboard and, personally, I've always just thought of it as sawdust glued together. It does NOT do well in wet environments.


    If I was doing a bathroom floor especially I would use 3/4" plywood instead. It will hold up a lot better in wet environments and the cost is minimal in comparison between them.

    Depending on where you live a sheet of 4x8, 3/4" plywood could run you up to $40.


    Sounds like you won't need more than two sheets for your space.

    Here are the comparisons between MDF and HDF

    The cost of these 2 would be determined by a visit to the store, you selecting a product you like and the sales person advising you on what the total cost would be for the product, based on square feet. They could also talk to you about water resistance and if it is good to use in a bathroom.

    My hubby used to work at Roseburg Forest Products and they make a product called medex which combination of moisture resistance, superior MDF board properties, and a formaldehyde free adhesive system.

    Suzanne: Please do not use MDF in a bathroom. It will be a mess in no time. MDF hates water. You could get the luxury vinyl that looks like wood, or peel and stick tiles or ceramic tiles. You will be much happier in the long run.

    MDF is not waterproof and you will find it hard to clean as well- it is not recommended for flooring- it is used mainly for vanities and window sills not for floors- we don't have pricing for materials you would have to look online at places like Home Depot, etc whatever stores are in your area to find out prices per sheet or square foot- MDF swells and again is not waterproof so not a good idea for floors. You would do better to add peel and stick tiles or vinyl it would be cheaper and work much better


  • I would not use MDF on a bathroom floor. Go to your local home improvement store and look at flooring for bathrooms.

    Do not use MDF or HDF. It's recycled paper and resins pressed under heat and pressure. It's not waterproof, swells, and shreds when wet. Use plywood

    Hi Sussane,

    HDF (Heavy Density Fibreboard). MDF (Medium Density Fibreboard) Not sure this would be a good flooring on it's own as it swells when it gets wet and will have to be replaced. Best wishes

    Could they have meant LVP? That would be much much better. MDF will swell and be ruined very quickly.

    Hello. Please reconsider using mdf. It is a composite wood product that would be aggravated by any introduction of water.

    MDF will swell and you will hate it in your bathroom. You don't want to put a lot of work into something that will ruin very quickly. Check out a waterproof floating floor. Sold at Home Depot or Lowes ....easy to put in and used in areas where hurricanes are common. I am considering this for a bathroom as well. They are interlocking and you don't have to use grout. To make MDF look good, it will be a lot of work.

    Hi Sussane, I wouldn't put MDF or HDF in the bathroom since they both absorb a lot of water and will swell up and get all moldy. HDF is just a higher density version of MDF (Medium Density Fibreboard)

    MDF would not be a good floor to use in a bathroom. It will absorb water, swell, and peel.

    Agree that MDF is NOT suitable for high moisture areas. I have used 1/4" plywood as a surface, smoothed the seams, and then covered the floor with 12" square self-stick vinyl tiles. You can get them for about $1 each. However, I prefer a tile floor in the bathroom.
