Hello everyone,
we are currently renovating the bathroom of our older building.
Due to the thin walls (the bathroom is in a dormer), the water supply and drainage pipes (both new) for the washbasin are surface-mounted on the wall.
We now want to build a stud wall in front of it ourselves. Since the bathroom is very small (5 m2 (54 sq ft)), every centimeter counts, so the stud wall should be as shallow as possible.
The plan is to screw four rows of 44 mm (1.7 inch) thick squared timber beams to the wall and then cover them with 15 mm (0.6 inch) OSB and 10 mm (0.4 inch) Fermacell boards.
The stud wall will be about 1.6 m (5 ft 3 in) long, 1.2 m (3 ft 11 in) high, and with tiles at the end approximately 90 mm (3.5 inches) deep.
Now the question is how best to hang the washbasin (mineral cast with cabinet).
My idea was to make sure that, at the height where the basin will hang, there is definitely a timber beam installed so that later two M10 hanger bolts can be screwed into the wood to hang the basin. The load-bearing section would then be about 60 mm (2.4 inches) thick (44 mm squared timber + 15 mm OSB).
I can’t say exactly how heavy the basin is at the moment. It is definitely mineral cast (so rather lighter than ceramic) and measures 70 x 45 cm (28 x 18 inches).
Do you think two hanger bolts anchored in 6 cm (2.4 inches) of wood can safely support the basin?
Best regards,
Simon

No, your method definitely holds up. My addition about the cavity anchors was only meant for my drywall example, which in turn was just to illustrate that your setup is rock solid.
So if drywall can hold that much, your construction will certainly hold even more.
That reminds me, in case someone else reads this who wants to work with drywall… It only holds about 100 kg per m² (2.2 lbs per ft²). So it holds more only if you have over 1 m² (10.8 ft²) of wall area as the mounting surface and the screw points are well distributed accordingly. If all screws are fixed within an area of 50 cm (20 inches), even the best anchor won’t help anymore…
