    I am removing two layers of linoleum in my kitchen and dining room for the purpose of putting in a tile floor. My home was built very well in the mid-60's on 16 in centers with 1 x 6 planks laid on the joists at at a 45 degree angle and what appears to be at least 3/4 inch plywood on top of that. I want to put down backerboard and tile this floor but the floor height after applying these layers seems to me would be too high. I will have to cut the french door and the pantry doors and there are three doors out of this area onto hardwood floors and each of those thresholds will have a significant rise. I can make comment on what I want to do, but what I want to know is what are you supposed to do. Is the height of the floor irrelevant in renovations like this?
    BTW: The linoleum in the kitchen area and the transition to the hardwood areas is level at the moment.
    Thanks,

    I guess with the thinset, backerboard, thinset, tile = ~1 inch? I guess it is not that bad, I just don't recall seeing it like this in other homes (I look at new homes for ideas and design patterns) :)

    The planking sub-floor is older lumber and are 1 x 6 running at a 45 degree angle with the floor joists. I can see this construction from the basement. I renovated my bathroom last summer and completely gutted the entire room, all the way to those planks. The original construction had put the tile in a mortar bed supported with mesh wire on just the planks. There was a layer of roofing felt between the planking and mortar bed. I took all of that out (down to the planking) and put in 3/4 inch plywood on top of the planking and then backerboard and then tile and there is about an inch rise as you enter the bathroom. I put a marble threshold under the door and the bathroom tile is about 1/4 inch higher than that.
    Back to the kitchen, I would like to remove the flooring down to the planks, make adjustments that need to be made there for support and lay a thinner, rigid underlayment of some type. I don't know what that would be. On top of that underlayment, I would begin the tile installation starting with the backerboard.
    Sorry, I am not familiar with the term 'saddle'. I do not want to remove the exterior door unless absolutely necessary. What to do about the threshold has everything to do with what is done with the floor/subfloor.
    And thanks for the replies and considerations ... I am not a pro at this, just a DIY guy. I am not against getting the pros if this is bigger than I realize.

    You don't need backer board just tile over the plywood. If you are going after the height you will want to remove the 3/4 plywood and replace it with your backer board but then the ship lap may be to flexible and you would change that to plywood. I would think you have a good floor just the way it is, just tile it.

    Thank you nealtw, that's kind of what I was hoping to hear!
    I have been given many suggestions, the best of which is just to tile right over the linoleum. Heck, I could start tonight if that is an appropriate plan of action.

    Remove the lino and check for squeaks as that old floor was just nailed down, I would screw thru to the joist and add shorter screws to tighten up the 1x6.

    That would save so much trouble but morter will never work on the linoleum.

    Is the linoleum glued down or floating?
    If glued scrap off the paper the best you can and sweep up floor really good before you start your morter tile.

    It was asked about the lino, yes, it is glued down. Scraping is how I removed a portion of it. This will probably be the hardest part of the job unless I remove the plywood. If I remove the plywood, I'll just cut it up in sections with lino glued on!
    I do not understand the part about the shorter screws. I was intending to use screws to get rid of squeaks. I am assuming that you mean to use shorter screws through the plywood to secure the planking to the plywood after the longer screws are used to secure the planking to the joists.
    Did I understand someone to say go ahead and remove the plywood and tile on the planking (using the backerboard in place of the plywood). I haven't thought of that but it would be a perfect solution, I think! :)

    Yes you can replace the plywood with the backer board. Put it down with thinset morter and screws.

    hey RD - I just completed a similar project in a 1962 home. It's more work, but if you ever plan on selling the house, I seriously recommend pulling up the ply. Wear a mask, set a circular saw to the depth of the ply, and cut it into workable chunks, right through the lino. If the ply/lino is original, it was likely put down with nails, and will come up easily in chunks with a crowbar.

    Once the ply is up, lay 1/2" hardie backer directly on the 1x6 sub floor, and tile on top of that. The transition between rooms will be almost exact, if you have 3/4" wood floors (depending on how many times they've been refinished).

    Check this out for the before: http://www.drunken-diy.com/where-demo-ends-and-rebuilding-begins/
    And the after: http:http://www.drunken-diy.com/how-not-to-lay-tile/

    The extra few hours is totally worth not tripping every time you walk into the room.

    my bathroom was like that... they layed lath over the vinyl. it held up quite well, but I wouldn't recommend it, as it is a real pain in the butt scraping that off if you ever want to change it up

    Big mistake, 1 X6's and linolium should never be under a tile floor. It's going to flex, and the thin set is not going to stick to the linolium.
    Less work to remove what you have down to the floor joist and use Advantec subflooring with constrution adhesive and screwed down with ceramic coated deck screws, then a layer of 3/8 subfloor rated plywood, 1/4 tile board set in thin set.
    Then to have to go back and remove all that tile when it comes loose, and the grout cracks.

    What Joe says is the standard but you have to be carefull here as sometimes people are causing a much greater problem here.
    The problem comes at each side of the room where the non bearing walls are sitting on the floor. These walls most times do not sit on a joist and is supported by the floor boards. When these board are cut close the wall and replaced unless steps are taken to support that wall it will sag and damage the floor on both sides of the wall.

    What is missing here is nobody said anything about if your putting down tile, with the weight added you need to check the bracing under the floor. To wide of spand will bouce and stap the tile.
