    Default Drilling FOUR holes into bath to fit Hansgrohe taps with porsadrill at 365-drills

    The guys at Hansgrohe have made life great for clients but difficult for installers. There is now a bath mounted tap unit for sale that will need four precision holes drilled to install correctly Here is an image of the taps. Note the layout and style can vary: But the base plate is the same !
    The important thing is that you are going to need six drills to install the holes for this unit.
    They are 2 x 30mm 1 x 35mm 1 x 50mm steel cutting drills plus 2 x 35mm 1 x 40mm 1 x 55mm diamond cores
    And plan on about 2 hours of work plus any travel time if you are paying to have the holes drilled.

    Lets make a start...

    First we used the chrome plate to help mark out the bath to drill the holes. The client wanted the TAP centered to the waste. Not the plate centered to the bath. So the holes we will drill are offset.

    Its VERY important to choose a bath capable of holding the 75mm plate. Its quite deep. If you have a shallow tap area the plate will stick out. Choose your bath wisely !
    Plate removed (and stored SAFELY) we mark the final position of every hole. We use indelible pental marker pens which do come off with baby wipes. Trust me a lot of holes have been drilled. This bath is a Kaldewei puro 687.
    We marked out the bath in critical detail. 110mm per hole. We then used diamond to grind down the enamel and expose the metal to dead center. This is where we put our pilot drills. We drill out all four pilot holes.
    You can see all four pilot holes drilled in the bath. The baby wipes have been used to remove all markings. It is better to work in a clean environment when drilling holes into baths,
    To get the markings you are better off to have part number 13444180 or 39449000 to guide you
    This is part that you need. as you can see there is some flex in the fixings but not the top mount
    The manual is quite details but you do need to read all the instructions.
    Its no good having this top part. There are no install instructions for this unit in this box.
    Make sure you reseal all the Hansgrohe boxes there are too many things to lose
    The holes should match the template above
    I believe we have drilled in all the right places. Hansgrohe fittings are difficult but if you follow the instructions
    Painted in enamel paint to prevent rust
    Looking great. Takes 24 hours for paint to harden. Do not install until next day

    Yes exactly. That shower set (hot tap : cold tap : spout and shower) is £1700 quid

    ANd the bath £600 quid!

    A lot of £££££ for a small item.
