Geneva alcove installation
Standard alcove installation: mortar bed (1"), ledger boards, drain to 1.5" PVC waste, tile surround. Grohe's installation documentation is available through authorized showrooms and grohe.com. The Geneva's flat-back interior simplifies tile measurement against the back wall -- the flat surface provides a consistent reference for tile layout.
Grohe faucet pairing
Grohe deck-mount faucets (Concetto, Allure, Essence series) pair directly with the Geneva's deck drilling. Verify faucet hole pattern (single, three-hole) matches the Geneva configuration ordered. Grohe's showroom staff can confirm the correct faucet and connection hardware combination for a specific tub and faucet pairing.
