Whole-project totals
Cost to Renovate puts full professional installations at $400 to $2,500, with a national average near $1,200, and a budget single-bed job around $350.1 Its tier table runs from $350 (one bed, no irrigation) to about $3,000 (custom stone or steel beds with irrigation). HomeAdvisor prices a broader professional flowerbed install at $1,000 to $3,000 for a 5×12-foot bed, so ask whether a quote covers a raised bed or an in-ground one.4
DIY or hire
A single raised bed is a beginner weekend project: cut boards, screw the corners, level the spot, fill with soil. Home Depot’s raised garden bed section shows current kit prices (plain link, not affiliate). Hire out only when you need stone or block walls, a large multi-bed layout, or heavy grading.3
