    Default diagonal vs. square installation estimate

    Does anyone have a rule of thumb for how much more tile a diagonal installation takes than a square installation in a given area? I haven't done a lot of diagonal installs but there seems to be more waste to cover a given square footage than doing the same area laid square. Also, how about labor time? I realize there are many variables at work here but I'm just lookiing for a ball parky percentage to suggest when customers ask about the two options.

    Thanks

    I'd start with 10% extra and to minimize waste I prefer to install diagonal floors with a square border. Too many variables for a price, you should try asking guys in your area for the going rates there

    My tile sub charges an additional 20% for a diagonal set.

    Might as well fill in the missing ..I figure 15% and thats usually dead on, also if its naturl stone like tumbled marble i get more out of my sq ft cuz I use my belt sander and hit the cut edges to round them like the rest of the tile..that works on diag or straight obviously. Thats another perc of using TM and the like.
    some people may say they figure 20% but that may be what they figure to add in cost not necessarily the exact waste or useage of material.
    You can say 20% to play it safe I guess but on expensive tile that extra 5% adds in a lot of $$$$$.

    I always figure 10% for straight and between 20-30% for diagonal,

    and yes you have to charge at least 1 or 2 dollars more per sqft for diagonal, more layout and cutting, its all gotta line up.

    every job is a different cost, and therefore each job must be considered carefully.


    large rectified porcelain or stone tiles on the diag. is a much more difficult job than 12x12 diag ceramic.
    we are installing very large 3' and 4' long tiles with rectified (cut square and straight) edges and 1/8" grout joints. That is a beast allready, if you are turning it to a 45 degree angle it is twice as much time.
    my rule of thumb is to consider every asspect of the job individualy.

    delivery, protection of work area, demo, substrate installation or prep, installation of the tile, grouting, sealing. each facet of this work requires different materials and time depending on the work in question.
    some sealers are expensive and need to be applied more than once. some are just for grout joints.
    some stuff is easy to install, some is not.
    some things are easy to grout. some are not.

    and so on.
    I work in mansions for celebrities, highrise buildings, studio lots, government buildings, schools. All of those are different and there is no magic number to use for a per sq. ft. charge.
    Do not use the crystal ball method of bidding.
    use a computer to set up items of work you do and track the per unit cost plus a huge profit. change those figures over the course of your career at least once a year to keep up with the inevitable rate of inflation.

    tile guys are notorius for not understanding these simple ideas.
    I use microsoft project and quickbooks to track, schedule, and job cost.
    I can tell you that used correctly a new world will open.

    Something that is often overlooked by installers contemplating a diagonal installation is the use of a border around the diagonal "insert". The insert becomes modular and requires only half or quarter cuts. The function of the border is two-fold: Frame the insert, and mask any inconsistencies at the perimeter of the floor.

    Layout and staging are a bit different for the diagonal with border, but all other aspects should be the same.

    In addition to simplifying layout problems, the diagonal-with-border arrangement requires the simplest cutting as opposed to running the diagonal tiles right to a field's edge.
