A turnkey bathroom of 5–6 m² with 4–5 fixtures costs 2400–3800 ₾ and takes 4–6 days before tiling. Prices are fixed per design, hidden joints carry a 5-year warranty. Plumbing comes within a full build project.
We run water supply and sewerage, install plumbing fixtures and filtration systems. We work with metal-plastic, polypropylene and stainless steel.
Only as part of a house project
We deliver this line of work only as part of a house project, when we build the house turnkey. We do not take it as a standalone order: a single warranty is only possible when one contractor answers for the whole chain of work.
About the work
How does stroydom.ge deliver plumbing?
Water supply, sewerage and plumbing fixture installation.
What is included in plumbing?
What is plumbing and why is it needed?
Plumbing is a pipe network under constant 24/7 pressure. The cost of error is a flood, mold, screed damage, often appearing a year later. Hidden joints cannot be re-tightened after finishing.
We design plumbing from real scenarios, use manifold distribution, embed service access. We pressure-test and provide a test act.
What stages does plumbing consist of?
Each stage runs only after the previous one is accepted — so hidden works are never "closed" before inspection, and a mistake never has to be hunted for through screed and plaster.
- 1
Distribution design
Diameter and flow calculation, pipe material choice, cold/hot water and sewer routing.
- 2
Route preparation
Chasing, slab penetrations, sleeves, manifold cabinet.
- 3
Sewer installation
D50 and D110 pipes with slopes, inspection points, fan pipe, slab noise insulation.
- 4
Water installation
PP, metal-plastic or stainless per design, manifold distribution with shut-off valves.
- 5
Pressure test
Water fill, 6–10 bar for 24 hours, drop monitoring, leak fix before closing.
- 6
Sealing and finish
Chase sealing with mesh reinforcement, ready for tile work.
- 7
Fixture installation
After finishing: toilets, sinks, baths, showers, faucets, water heaters, machines, filters.
- 8
Start-up
Loaded run, sewer check, pressure adjustment, operation briefing, leak warranty.
How does stroydom.ge control quality on site?
How we work on site — materials, equipment, tolerances, documentation and acceptance of hidden works.
Materials
Certified Rehau, Uponor, Wirsbo, Wavin, Geberit pipes with 25–50 year warranty.
Hidden joints
Hidden joints: only permanent (soldered or press-fit). Threaded joints in service zones only.
Noise insulation
Sewer riser and horizontal pipes wrapped or replaced with Wavin AS silent pipes.
Leak protection
Optional Aquastop system with leak sensors and automatic shut-off.
Documents
As-built distribution scheme with wall references, pressure test act, equipment passports.
What should be accounted for in Tbilisi and Georgia?
What we account for here: seismic intensity 8 (MSK-64), hot summers and damp winters, steep terrain, older stock with timber floors and worn city networks.
Hard water
In Tbilisi hardness 7–12 °H. Mechanical filter 100 μm + softener; otherwise heaters burn in 2–3 years.
Pressure differences
In old top floors pressure drops to 1.5–2 bar; in new low floors rises to 7–8 bar. Pressure reducer on intake and booster pump if needed.
Old risers
In old stock cast-iron sewer risers have narrowings and deposits. We replace risers with Skolan polypropylene where possible.
Seismic compensation
On long horizontal water runs compensators or P-shaped bypasses to prevent pipe rupture from movement.
Slopes on hillsides
In Vake, Saburtalo, Bagebi external sewer needs precise slope and inspections every 10–12 m.
How much does it cost and how long does it take?
Indicative price ranges in lari (₾) for standard conditions. The final estimate is fixed after measurements and specification approval.

Frequently asked questions — Plumbing
Why can threaded joints not be buried in a wall?
Every demountable joint loosens over time: the seal settles and the metal moves with temperature. You cannot tighten it inside a wall, and the leak announces itself as a damp patch in the flat below. So everything that gets covered by plaster and screed is joined permanently (soldered or press-fitted), while demountable joints stay in a manifold cabinet or behind an access hatch.
What is manifold plumbing and why use it?
With a manifold, each fixture has its own pipe from a central manifold with an isolating valve. That gives stable pressure (a tap in the kitchen no longer affects the shower), the ability to isolate one fixture without shutting off the house, and no joints inside walls at all. It costs 20–30% more than a tee layout and pays for itself the first time a repair needs no wall opened.
Is pressure testing mandatory, and what does it show?
It is mandatory. The system is pressurised to 6–10 bar (one and a half to two times working pressure) and held for 24 hours. Any pressure drop means a leak, visible on the gauge long before it becomes a drip. The test is done before the chases are filled and recorded in an act; without that act the routes are not closed.
What is the water like in Tbilisi, and is a filter needed?
Hardness in Tbilisi runs 7–12 °dH: the water is hard. Without treatment, scale destroys a water heater element in 2–3 years, blocks tap aerators and leaves white deposits on fittings and shower glass. We fit a mains mechanical filter and a softener; the payback is roughly one water heater.
Why does the drainage smell?
Three typical causes: insufficient fall (2–3 cm per metre is the norm for 50 mm pipe), a trap siphoned dry because there is no vent pipe, and a dried-out trap in a rarely used floor gully. The first two can only be fixed by rebuilding, so we verify falls and venting during installation and photograph them before covering.
Do drainage pipes need acoustic insulation?
A soil stack in a residential building is a noise source audible in every room next to the duct. Ordinary grey PVC transmits sound directly. We use low-noise pipe with mineral filler or wrap the stack in acoustic insulation. It cannot be done after the finishes, because the duct is already closed.
