Do not rely on the product title alone
Two products with similar names can require different concealed bodies, hole patterns, connection methods or installation depths. Use the manufacturer model number and current installation document when available.

Owner-supplied does not mean compatibility is assumed
The written scope should say who verifies the product, who supplies adapters or missing parts, how delays are handled and how product warranty differs from plumbing workmanship.
No specific product is recommended without the actual project dimensions, model information and scope.
