Glass Bath - 4.5" Glass Downstem

The Glass Bath 4.5" Glass Downstem is a clear glass replacement downstem for a bong or water pipe whose original stem chipped, cracked, or went missing. It slides into the joint of your piece, and the slitted design breaks water into many small bubbles instead of one big gurgle. That gives the smoke more contact with the water, so it cools and filters the way the original stem did. At 4.5 inches, it is sized for taller water pipes and beaker bases that need a longer reach to sit just above the water line.

If you want a like-for-like swap rather than a whole new piece, this is a simple fix, and you can browse the full Glass Bath collection for more from the brand. If you would rather refresh more than one part at once, the Glass Bath Kit and the Glass Bath 20-300 Kits are worth a look.

In our opinion, this downstem is best for anyone with a taller piece who wants the original smooth, cooled hit back without paying for a new bong. A broken stem takes an entire piece out of rotation, so a spare glass downstem is an easy fix to keep on hand.

Keep in mind that this is a glass part with a glass-on-glass joint fit, so it needs a gentle hand. It should slide in snugly and never need force. Jamming it in can crack the joint or fuse the glass together, so confirm your joint size before you push harder. Length matters too: a stem that is too short will not reach the water, and one that is too long can crack against the base.

Before you order, measure from the bottom of your joint straight down to just above the base, without touching it. If that distance lands close to 4.5 inches, this stem should clear the water properly. If the slits are cut into only one side, face them toward the water so the diffusion happens where it should.
