Best caulk gun for bathroom and kitchen touch-ups
Which gun to buy for re-caulking a tub, sink or trim, and when a cheaper or stronger one makes more sense.
For most bathroom and kitchen jobs, buy the Newborn Octogun 930-GTD. It has the right amount of push for latex and silicone, it's comfortable to squeeze, and its rod pulls back on its own when you let go, so the flow mostly stops without an extra step.1 2 3
If you also work with thick sealant or construction adhesive, or gripping hurts your hands, get the Newborn 250 instead. A battery gun like the DeWalt only makes sense for big jobs, and only if you already own the batteries. For one small repair, skip the gun and buy a squeeze tube.2

Newborn Octogun 930-GTD Hex Rod Cradle Caulking Gun
Good fit if: tubs, sinks and trim with latex or silicone
Model 930-GTD
- Comfortable, easy squeeze
- Rod pulls back by itself
- About half the price of the 250
- Frame doesn't revolve
- Weak on thick adhesive
- Can still drip a little
A 10:1 gun suits the thin caulks you use indoors. Practical Sailor's team prefers that range for latex because the bead comes out smoother, and Bob Vila's reviewer gave this gun the best grip of the eight they tried.1 2
The feature to pay for is the clip that pulls the rod back when you release the trigger. You don't have to reach for a thumb lever at the end of every bead. It stopped cleanly in two YouTube demos, once with silicone and once with latex.4 5 It isn't truly drip-free, though. It dripped a little in Bob Vila's test, which was run in near-freezing weather.1
Its main drawback compared with the 250 is the fixed frame, so you have to stop and turn the gun at tub corners.1 It also isn't the right tool for polyurethane or construction adhesive.2
Verdict: Buy this one if you mostly caulk tubs, sinks and trim. It does that job well for about half the price of the 250 at the sellers we checked.3 6
Newborn 250 Smooth Rod Revolving Frame Caulking Gun
Good fit if: polyurethane, adhesive, cold weather or weak grip
Model 250
- Less force on every squeeze
- Smoothest revolving frame in Bob Vila's test
- Handles thick products
- About twice the squeezes per tube
- Costs about twice as much
- Drips a bit
This is the gun contractors tend to own. Practical Sailor calls it probably the most popular among them, and Bob Vila's reviewer made it their top pick.1 2 At 18:1, each squeeze takes much less force, which matters with thick sealant. In one builder's side-by-side, it moved no-sag sealant far more easily than a cheap 6:1 gun.7
The revolving frame is the other reason to buy it. The tube turns in the gun, so you can follow a tub corner without changing your grip. Bob Vila's reviewer found this frame the smoothest of the group.1
For plain latex, it's more gun than you need. You pull about twice as often per tube as with a 10:1 gun, and Practical Sailor gets smoother latex beads at lower ratios.2 One thing to check before you buy: some sellers list a zinc handle and others a steel DuraCore version, so the gun you get may differ from the one that was reviewed.6 8
Verdict: Buy this if you want one gun for everything, or if squeezing hurts. Skip it if you only use latex and silicone.
DeWalt 20V MAX Cordless Adhesive Gun (tool only)
Good fit if: deWalt owners running many tubes
Model DCE560B
- No hand strain on long runs
- Six speed settings
- Light on battery, per one owner
- Heavy and long, poor in tight spots
- Loose puncture spike
- Poor value next to rival battery guns
On a long job, this gun earns its keep. One owner called it a huge forearm saver on a 50 to 75 foot run, and another said the powered feed avoids the lumps a manual gun can leave.9 10
It's the wrong tool for a bathtub, though. It weighs 4.6 pounds before you add a battery and it's about 21 inches long, so it's awkward in tight spots like under a sink.11 Three owner videos also complain about the same loose puncture spike, and one says the anti-drip doesn't work well.9 10 12 In the one bench test of cordless guns we found, the tester ranked it last among the guns that survived, mainly on price.13
Verdict: Worth it only if you already own DeWalt 20V batteries and have a lot of tubes to run. For everything else, a manual gun is the better tool.
How to choose
Match the thrust ratio to what's in the tube
Thrust ratio is the gun's leverage. On a 10:1 gun, each pound of squeeze puts 10 pounds of force on the tube.14 A higher ratio makes each squeeze easier, but each one moves less caulk: one chart lists 18 to 22 squeezes per tube at 10:1 and 34 to 40 at 18:1.2
Use about 10:1 for latex and silicone. Move up to 18:1 or higher for polyurethane, construction adhesive and roof tar, especially in cool weather.1 2 14
Go higher if your hands get sore
A manual gun can take real force. One workplace ergonomics case study measured more than 20 pounds of grip on every non-silicone caulk it checked.15 If gripping hurts, a higher ratio is worth the extra squeezes, even for thin caulk.2
Don't expect zero drips
No gun stops every drip, because part of the problem is in the tube. Trapped air and thin caulk keep pushing after you let go, and a hole cut too small makes it worse.14 16 Two guns sold as dripless dripped in Bob Vila's test.1
To check, take the tube out of the gun. If caulk still runs, the gun isn't the cause. Storing tubes upright and tapping them on a hard surface before loading can help.16
Look for a long puncture rod
Short rods on cheap guns may not reach the seal inside the tube.17 Built-in cutters matter less. One mangled the tip in a side-by-side, so keep a utility knife nearby.7
Others we looked at
- Bates Choice 10:1It was the only gun that didn't drip in Bob Vila's test, but that was one cold session, and the same reviewer found the grip uncomfortable. Check the thrust ratio on the listing before you buy.1
- Dripless ETS2000A 12:1 gun with a rotating barrel. One painter says his have survived drops from ladders and roofs, so it's a fair choice if you caulk often.17 18
- Tajima Convoy LightFine Homebuilding's editor likes its very low weight and hanging hook, which help on a ladder.19
- Cox Ascot 41004-2TA 26:1 gun recommended for thick materials. That's far more than bathroom caulk needs.2 19
How we picked
We haven't tested these guns ourselves. We found no measured lab comparison of manual caulk guns, so these picks come from side-by-side reviews, trade advice and owner videos. Drip results come from single sessions, and we don't have long-term reliability data, so treat them as a rough guide. A CPSC recall search on November 5, 2026 for caulk guns, Newborn, Bates and DeWalt showed no caulk gun recalls.[s39]
