Steinway Model S Piano: What It's Worth in 2026, Prices & Listings

Size: 5'1" (155 cm) baby grand
Made: Introduced in 1936 as Steinway's smallest grand; still in production

The Steinway Model S is the smallest Steinway grand, introduced in 1936 to bring the Steinway name into ordinary living rooms during the Depression. At 5'1" it is a true baby grand, and it carries the full Steinway action and build quality.

Used S grands are common and are the entry point to Steinway ownership. Their value is limited by size — short bass strings — not by quality.
