Crosslinks

Re: Crosslinks 20" Teak wood folding shower seat bench Part# HOM501102. Looks even better than we expected! Only one question: What kind of caulking do you recommend? Pro Installer tried a white silicon but it looked terrible so I removed it. The gap is quite large between cap and wall. Is that normal? Does it have to have caulking? The cap moves a little but thought that had something to do with making the seat stay up when not in use. Contractor threw directions away so can't refer to that info. Any chance you can email them to me? Thanks G. Callahan
