Decided I would move ahead & replace the bath with a P shaped thing & stick a shower in. I noted the advice on McAlpine parts & was going to order this part. Took the bath side panel off & had a WTF! FFS!! moment. What is in place is a big kitchen sink trap, & the plumber has hacked out an 8"x15" space from the floorboards so it has somewhere to hang smiley-face-shaking-fist So I guess the new one doesn't have to be a low-pro trap.... Anyway the existing white waste pipe is 43mm (external diameter) according to my micrometer, any advice on a correct trap for this gauge? The one I was looking at says it is 40mm. Or is that internal..? |

Bath wastepipe and sink wastepipes are both 1 1/2 inch or 40mm, Solvent weld pipe is slightley bigger than pushfit pipe but they both fit any standard bath trap or sink trap,

& in a related question what is the best thing for cutting tap holes. The bath is acrylic. I've seen some diamond coated bits.

Hole cutter
Measure twice - cut once

That's spot on for £6, I have some hole saws from a cheap 200pc drill bit set I bought in a pub about 20 years ago, they're going to be proper cheap tat but still going strong all these years later. Rarely use them on wood, sometimes plasterboard, but the most used is the 25mm one for bath tap holes. It's always twitchy bum time drilling tap holes, measure twice as Rocketman says, mark out and offer your bath filler up to your marks before drilling. Been doing a bath today and was pleased as punch when I saw that it already had tap holes, it's rare nowadays when they have the holes already. |

Thanks for the feedback everyone. I will add that set to the cart arfurchrysaik - & good to hear it is the 25mm I will want.  I had seen this. Maybe that is a bit much for acrylic but seemed a decent price. I will need to practice, I may even test it on the old acrylic bath which will give me an idea of how the thing feels on this material type. No room for mistakes on this as you rightly say! Dreading it & looking forward to trying. Hows that for conflicted?  |

That diamond tipped bit you posted would definitely not do a nice tap hole, it's for masonry/ceramics.
Pilot your holes with a standard wood/metal bit that is a little smaller than your holesaw pilot, that way you'll know you're drilling in the right place even when the hole saw is blocking your view.

Thanks jcplumb for confirming my gut response. I been looking at the diamond stuff as I had considered pipework behind tiles then thought it would be too much for a novice... I'd been thinking acrylic could be more like wood to cut, but then I wondered about the 'slippery' surface. Appreciate the tip on pilot hole but really wish you had posted your CBA comments on baths before I hit the buy button on the lump due to arrive this week   |

Just spent 3 days stripping paint off plaster for tiling. I have the McAlpine lo-pro trap & everything else lined up, but no mixer/taps so cannot start install. The clever courier seems to have 'lost' them. Thought you might like to see the existing trap install - quality workmanship! I nearly kept the existing tiles - they must be special ones - no grout needed - but decided against it.  Was quite surprised that the primer for tiles is in fact the blue milk from Tatooine. (So thanks to Skywalker Imports). Had some in my tea.  |

Are you keeping those 1970s "Chicken Tiles" on des? Chicken Tiles were very popular during this period. If you look closely at the pattern on them you can make out the shape of a chicken. Some tradesmen would say that you have to make sure that you get them all the right way up when installing them. Whilst others would say you have to remember to give each them a twist when fitting because a line of marching chickens look chronic. Not seen any for ages these days....Bring back "chicken tiles" is what I say ! Tappy, |

doing that period of plumbing many floor were butchered because 'shallow' traps were frowned apon because they did't give a 3 inch water seal as required by water by laws, since then mc calpines developed the 'long instead of deep' trap and also a lot of diyers use the shallow trap that does not conform but don't give a fuck, After all, a mans house is his castle and many time the trap is not considered untill after its fitted and the diyer can't fit a 3 inch trap because of the floor so goes back to the shop and asks " have you got one of those white bent things that will fit under a bath for the waste ", |
