Designed for Tight Spaces
The Knight fits where other hot tubs can’t—through standard doorways, onto small decks, into rooms that weren’t designed for spas. Its elongated 72 x 88 shape creates surprising comfort for up to five people who want to stretch out, not curl up. The full-length lounger delivers head-to-toe coverage, and the compact footprint means you don’t need to sacrifice your entire backyard.
Price range: $8,495.00 through $11,695.00

Smart Design for Real Spaces
The Knight solves the problem that stops most hot tub purchases: where does it actually go? At 72 inches wide, it fits through standard doorways and navigates hallways that larger tubs can’t. Perfect for indoor installations, older homes with narrow access, condos, or small decks where every inch matters. The elongated shape delivers full-body relaxation without demanding the footprint of square or round designs.
Inside, the full-length lounger cradles you from head to toe while up to 17 jets target shoulders, back, and legs. The compact 250-gallon capacity heats quickly and costs less to run than larger models—making daily use practical, not indulgent. Four additional seats mean family and friends fit comfortably without crowding. The narrow profile that makes installation easy also creates an intimate soaking experience.
Three Ways to Own a Knight
Choose the configuration that fits your needs. Industry Standard delivers Royal Spa quality at entry price—same warranty, same Indianapolis manufacturing, same support. Hybrid adds a three-pump efficiency system that saves over $1,000 yearly for quieter operation and decades of reliable performance. Medical build is not available for Knight.
Engineering That Proves Itself
The Knight’s Bio-Lok® Microbe Shield protects the shell at the molecular level, while ozone purification keeps water fresh between uses. Epsom salt compatibility—exclusive to Royal Spa—proves the quality of materials and engineering other manufacturers can’t match. Standard serviceable components mean any qualified technician can perform repairs without waiting weeks for proprietary parts from distant warehouses.
Royal Spa’s 40-year structural warranty backs the Knight with engineering confidence competitors offering 5-10 year coverage can’t provide. Made in Indianapolis since 1981, every Knight is custom-built one at a time with your choice of shell colors, cabinet finishes, and upgrades like waterfalls, LED lighting, or stereo systems. Standard coverage includes 10 years on surface, 3 years on parts, and 40 years on structure.
