17 of the 43 live towel bars here that print a length in the 600mm class actually print 600mm. Eight NTL bars print 595 or 598mm, and 18 others print anywhere from 620 to 665mm. The 600 in a title or model code names the class; the size line on the listing is the length.
The short version
Go by the size line on the listing, not the title or the model code. Of 43 bars in the 600mm class, 17 print 600mm, 8 print less and 18 print more, up to 665mm. On NOBEL's nine models sold in both sizes, 750mm costs $4.50 to $9.00 more. And 30 of the 90 live towel bar listings print no size at all.
Only 17 of the 43 bars in the 600mm class print 600mm

90 active listings titled towel bar, censused 17-09-2026: 117 in total less 15 draft and 12 archived. 60 print a size line and 30 do not. Of the 60, these 43 print 595 to 665mm, 13 print 750 to 855mm, and 4 are left out because their size lines contradict their titles.
600mm is the most common single figure, and it still covers under half the class. Eight NTL listings print 595 or 598mm. Aalto prints 600mm on three listings and 645 to 665mm on the other eight. Put NTL's S31011-B next to Aalto's ATBEK11 and two bars sold in the same class are 70mm apart.
Is a 600mm towel bar actually 600mm long?
Only sometimes. Of the 43 live listings here that print a length between 595 and 665mm, 17 print exactly 600mm. Eight NTL bars print 595 or 598mm, and Aalto's ATBEK11 prints 665mm.
Three NOBEL '600' bars print 630mm, and four listings contradict themselves
| Listing | What the title or code says | Size line as printed |
|---|---|---|
| NSS-01-600 | 600 in the code, single bar | '630 x 60mm' |
| NSS-02-600 | 600 in the code, double bar | '630 x 120mm' |
| NWN-02-600 | 600 in the code, double bar | '630 x 130mm' |
| ATTMA11-800 | 800 in the code | '855 x x 65 x 55mm' |
| D401103-85 | 'Single Towel Bar 850mm' | '854 x 65 x 45mm' |
| D401104 | Double Towel Bar | '654 x 65 x 45mm' |
| D401104RG | Single Towel Bar | '654 x 120 x 45mm' |
| NWN-01-600 | Single Towel Bar | '600 x 220mm' |

Size lines as printed on 9 live listings, read 17-09-2026. The last four are left out of every length count in this guide, because the title and the size line cannot both be right.
NOBEL's N90001-600 and N66011-600-GM print 600mm. NSS-01-600, NSS-02-600 and NWN-02-600 carry the same 600 in the code and print 630. The longer class drifts too: Aalto's ATTMA11-800 prints 855mm, and Dusche's 850mm single prints 854.
The Dusche D401104 pair is messier. D401104 is titled a double bar but prints the same size line as the single D401103. D401104RG is titled a single bar and prints 120 as its middle figure, which is what the longer Dusche double, D401104-85, prints. On each, one of the two fields is wrong and the listing gives no way to tell which, so neither is counted. NWN-01-600 prints a 220mm second figure on a single bar, and ATTMA11-300 prints its length as 3.00mm.
Does a 600 in a towel bar's model code mean it is 600mm long?
Not on every listing. NOBEL's N90001-600 and N66011-600-GM print 600mm, but NSS-01-600, NSS-02-600 and NWN-02-600 from the same brand print 630mm. Measure against the size line, not the code.
The length comes first on every size line, and NTL shuffles the rest
| Brand | Size line as printed | Listings printing a size | What the figures tell you |
|---|---|---|---|
| NTL | 'Size : 598*53*127.5mm' on R42012GM, 'Size : 598*127.5*53mm' on R31012 | 10 of 10 | Length first; the other two figures swap places between models |
| NOBEL | 'Measuring 600 x 75mm', inside the description text | 30 of 30 | Length, then one more figure; only NNB-1208-BK labels them, 'L620 x W70mm' |
| Aalto | 'Size: 665x65x65mm' on ATBEK11 | 14 of 30 | Length first, then two figures; AT803M prints '600x70x120mm' |
| Dusche | 'Size: 654 x 65 x 45mm' on D401103 | 6 of 6 | Length first, then two figures |
| G.Ferretti, VERA, VERA CERAMICA | Model and finish only | 0 of 14 | Nothing to measure against |
The 90 active towel bar listings by vendor, censused 17-09-2026. 60 print a size line and 30 do not: 16 Aalto, 6 VERA, 6 VERA CERAMICA and 2 G.Ferretti.
All 56 listings counted in this guide put the length first, so the first figure is the one to hold against your measurement. After that there is no standard. NTL's R42012GM prints 53 before 127.5 and its R31012 prints them the other way round, and neither labels its figures, so the second and third numbers on an NTL listing can't be read as any particular dimension. NOBEL puts its size inside a sentence in the description rather than on a line of its own.
Which number in a towel bar's size line is the length?
The first figure. All 56 live listings here that print a usable length put it first, from NTL's '598*53*127.5mm' to Aalto's '665x65x65mm'. The order after that is not consistent: NTL's R31012 prints '598*127.5*53mm'.
Do all towel bar listings print a size?
No. 30 of the 90 active towel bar listings here print no size: 16 Aalto, 6 VERA, 6 VERA CERAMICA and 2 G.Ferretti swivel bars. Aalto's Enna AT802 and AT803 print one only on their Brushed Steel listings, AT802M and AT803M.

The 9 NOBEL models live as both a 600 and a 750 listing, censused 17-09-2026 and sorted by step. Prices were pulled live that day and can change; the product page carries the current figure.
Seven of the nine steps buy 150mm. The two NSS pairs buy 120mm, because their 600 listings already print 630. Dusche prices length the same way on its single bar: D401103 is $45.00 at 654mm and D401103-85 is $55.00 at 854mm.
Inside NTL's 598mm range, price moves with finish and bar count instead. The chrome R31012 double is $43.00, the gunmetal R42011GM single $67.00 and the black R41012B double $85.00.
If the space you measured is short of 600mm and you want two rails in gunmetal, order the QQNTL-R42012GM double towel bar at $81.00 as at 17 September 2026. It prints 598mm, and no other gunmetal double here prints a length under 600mm. For one rail in the same finish, the QQNTL-R42011GM single towel bar is $67.00.
How much more does a 750mm towel bar cost than a 600mm one?
On NOBEL's nine models listed in both sizes, $4.50 to $9.00 more as at 17 September 2026. The N90001 single goes from $40.50 at 600mm to $45.00 at 750mm, and the N63012 matt black double from $62.25 to $71.25.
Which gunmetal double towel bar prints a length under 600mm?
The QQNTL-R42012GM, at $81.00 as at 17 September 2026. Its listing prints 'Size : 598*53*127.5mm'. The other gunmetal doubles that print a length, N66012-600-GM and NNB-7302-BK/GM, both print 600mm.
