Sirius Design Centre operates from 197 Coventry Street as the exclusive Australian distributor for TOTO, the Japanese bathroom brand known for its washlet toilets and bathroom technology developed over more than a century. The showroom displays TOTO's toilets, washlets, basins and showers alongside fittings from Hansgrohe, giving visitors a chance to see and test bathroom technology that's difficult to properly assess from a brochure, particularly washlet functions and water-saving fixtures. Staff handle both retail sales for individual homeowners and commercial project enquiries, with installation advice available for trade clients working through a larger specification. A separate service line handles warranty and repair enquiries for existing TOTO product owners. Trading Wednesday to Saturday, with Monday and Tuesday by appointment only, the showroom's hours suit a planned mid-week or Saturday visit rather than an early-week drop-in. Sitting on Coventry Street among several other kitchen and bathroom brand showrooms, Sirius Design Centre is a useful stop for comparing premium sanitaryware options as part of a broader bathroom renovation project in South Melbourne's design precinct, and trade clients can discuss installation requirements for larger commercial fit-outs directly with staff.
