This polypropylene bowl is perfect for mixing adhesive or grout.  It has a 2 litre capacity, is 10cm high, and measures 25.5cm across the top. A great bonus: left-over mix can be allowed to dry in the bowl, and a quick squeeze of its flexible sides will crack any dried up residue allowing it to be scraped out easily. For once, you can feel fine about not clearing up after yourself as soon as you finish work
